Do you run headers ? [Archive] - The Supercar Registry

Hello,
I am really thinking about installing some headers on my stock 70 LS5 Chevelle. The exhaust manifolds that are on the car are not the right ones and will have to come off at some point anyway. This is a #'s matching style car that is driven just about every weekend. I am not too worried about changing gaskets if needed. Call me crazy, but I love stock appearing musclecars wih a nice sounding aftermarket exhaust along with headers. But I also like the simple and correct look of the factory exhaust manifolds. (I would have to find the correct ones of course..)
So my question is this... Who all runs headers on their mostly stock/restored cars?

my car is all Stock with only the headers being the non stock item on the car.
i bought my car this way and plan to enjoy the sound of the headers for now.
but in a few years i do plan on putting the original manifolds with the smog set up back on,which i got with the car.
i still prefer the look of the stock set up over the headers but i will miss the sound of my headers when the time comes for the change.i will have the stock manifolds hooked up to a chambered exhaust system so i can still enjoy that rumble when i do change over.

I really like the sound of a BBC when you can hear the headers tubes ringing at idle. Exhaust sound, especially muffler choice is very subjective. But if you like a nice aggressive exhaust, headers are right.

I'm a big fan of the day II look. A good aluminum intake, Holley carb, old set of white colored headers is a pretty timeless look. It's your car so do what turns you on, but you've got my vote for a set of headers http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

My car is mostly stock with a few Day II items (headers, wheels, distributor). My machine is on the loud side which is how I like it. However, I will likely be going back to the stock manifolds and exhaust at some point in the future. Can't say right now when that might be though.

So just curious. If you like the sound of headers then why put the exhaust manifolds and smog back on? For judging? Or maybe value?

Run the headers. They are a bolt on item. I like the Day-2 look for my 69 Z. Everything I did to the car can be changed back in one weekend if need be. Headers, wheels,Accel cap and wire kit, flex fan, traction bars etc. I own a survivor 1969 SS nova with the smog and the dog dish caps. That is boring enough for me! http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

for me its just preference in being stock 100% when the headers come off.
my car is all ready original with stock tires/interior/motor components etc...
so i really want to go that extra mile to have the car back in its original state.
as far as judging goes,yes it does help if your into that and it also increases value to have all your stock manifolds with smog system,especially if its a high horse motor like mine.
IMO i just think i give more respect to the guys that restore there cars back to original rather than having day 2 stuff on the car,so i plan on going back to the original set up myself. just my 2 cents

Hey Sam
I'd be more then happy to trade you my headers for your boring ol smog system. http://www.yenko.net/ubbthreads/images/graemlins/haha.gif

My plans are to find the original manifolds, but probably just put them on the shelf. I really enjoy the sound of the headers on the big block. http://www.yenko.net/ubbthreads/images/graemlins/beers.gif

Salvatore

03-18-2010, 07:59 AM

Nothing wrong with having the original stuff on the shelf. Remember not many of these cars stayed with the all original parts on them for more than a week or two. Don't know of ANY musclecar in my day that did not have at least a set of mags put on. Too many cars get restored today and lose their real identity. Do what makes you happy! http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif Worry more about fun than value for now.

-----Sam,,,The headers do bolt on, but you also have to cut the front pipe and do a bit of welding. That might be something to keep in the back of ones mind. For instance, if I had just spent the bucks install a Gardener setup I sure wouldnt be hacking on it. On the other hand if the front pipe is already compromised the decision would be a bit easier.
-----I had headers on my 64 421HO GP for the first several years and never liked them because the pipes hung down low enough that I had to be careful going over certain bumps or risk flattening a tube or three http://www.yenko.net/ubbthreads/images/graemlins/thumbsdown.gif.........Bill S

My personal taste is going back to manifolds. I appreciate the stock look (especially with smog). Less leaking. Also, when you see a car that appears ALL stock yet runs like a scolded monkey, http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif that's an attention getter.

Another option is to run headers and leave on the air pump system. This is a picture of Joe's original 1969 SS350 Nova (novajoe). You have to see it in person but it has the right look and this car runs hard.

Salvatore

03-18-2010, 09:19 PM

Bill, I would never hack a Gardner system for headers. There are many cheaper exhaust sysyems out there for a header installation. Good headers do not leak and do help performance with a few more small adjustments. Gets kinda boring when I go to these shows and see a couple COPO's, maybe a couple Yenko's and few Z/28's and maybe an LS6 car along with some L78's etc. all lined up with perfect factory restos it gets cookie cutter and a little stepford for me at times. No imagination from the owners, most just seem to be worried about how much their car is worth or not worth with the changes. If the car is a complete frame off resto it is not really original anymore anyway. But this is JMO!

Very well said Sam. I feel the same way.
I get kind of a kick at guys that say my car has 40k original miles. BUT it has been completely restored. The miles do not mean diddly if the car has been redone.

Having all of the correct stuff is awesome. But these cars ran around back in the day loud and proud. I like musclecars that scare old ladies when you go roaring by. LOL! My survivor Z has a set of headers that were installed in 1974. That and the Dixco gauges were done on the same day. I just love it! Would not even think of putting the smog stuff back on. Just my opinion....

While I like the look of a restored car, we drive ours and I too am a Day 2 guy who likes to have a musclecar that looks the part. As a matter of fact, Dale and I were out for about a 30 mile run in the old 396 car today. The first run since last October. Our 427 car ran Hedman headers from Day 2. We had a '72 with a '68 L78 and headers. Our '69 396 car has the headers that came on it in '97. Our '69 el Camino also got headers when I was freshening it up. The 455 in our '72 Lemans Sport got them too. My only experience with Hooker was that the collectors were way low. The Flow Tech headers started showing rust after one season. If you want to buy a nice fitting header, go with Hedman or others that fit, then take them to a company that does ceramic coating. The results seem to be a lot better. Flushed with money, go with stainless steel headers. They should last a life time, or certainly longer than us old guys are going to be around. http://www.yenko.net/ubbthreads/images/graemlins/wink.gif

I used "FIT" very loosely. All header fit is bad. Some are impossible. Some of the manufacturers forget that you mightwant to change sparkplugs, or even use plug wires. Then there are those that hit on everything and need to be massaged with a ball peen hammer. I just found the Hedmans the least bad....if that makes sense. I can see why people stay with manifolds. Thankfully unleaded gas cuts down on the plug changes. On our L78 I've only changed plugs once in the 34K miles that we have had the car. http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

03-19-2010, 09:40 PM

Bill, honestly I have Hooker SC's on my 1969 Z/28 non power steering car and they really fit quite well. They are even the bigger tube style. In the old days it was tougher I think but lately if you buy a good header they fit pretty well. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

-----I dont know if Tom is still running them or not but back when I put the raised-port A/R head engine in Red Alert I really wanted a set of step-headers as well. A guy that used to work for Lemons Headers in Ca. and had gone out on his own got refered to me. We talked, and he said he could do the job without the car. He said "I have all the dimensions"..... Ill never forget those words!!! I got the headers and after a couple of weeks of tweeking got them on. Thank God Red wasnt a plug-eater though as the plugs were about a 4 to 5 hour job with all the expected cursing and skinned knuckles. Add into the mix the 14 to 1 pistons that required very good plug indexing. That amount of time never went down either. I would have way rather pulled the engine. He//,,,That was easy.......Bill S

03-20-2010, 04:25 AM

You just can't go wrong with a regular set of Hooker Competition #2455 for a Big Block Chevelle. They are reasonably priced at only $165 un-coated and are a one-piece design with no separate tubes. They install very easy and have great spark plug access even with their 2-inch Primaries. Hooker Competition Headers also have thicker pipe thickness for better durability than the Super Comps. I have owned and installed many sets of Hooker Headers and have NEVER had to take a hammer to them for "adjustments". This speaks volumes.

Just mounted PN# 2457-3HKR - 2" Hooker Competition Darkside Ceramic Coated Headers on the Black Camaro.

http://www.summitracing.com/search/Make/...hooker+darkside (http://www.summitracing.com/search/Make/CHEVROLET/Header-Style/Full-length/Model/CAMARO/Year/1969/Engine-Size/7-4L-454/?keyword=hooker+darkside)

The clearance around the steering box was very good. On the driver side I removed the oil filter, clutch rod between the Z bar and clutch fork. With the front end up a couple feet they went right in from the bottom.
I relocated the clutch return spring much like a SB Camaro would be, fabbed a extension out of 3/32" piano wire. It now runs right between two of the four tubes and is terminated near the SS brake line that runs across the back of the subframe crossmember.

Passenger side has good clearence around the starter. The outboard lower area came very close to the original fuel line that runs along the inside of the sub frame on a 69 Camaro.
Some of you guy's ain't going to like this. I rerouted the fuel line along the top of the subrame much like a 68 BB Camaro is. I made a new line from SS and spliced it in at the outside frame rail under the Pax seat. The joint looks like what is found on a 69 Nova, 3/8" hose W/two green clamps. Also had to trim 3/8" off the rear bolt on the upper control arm.
Here is the pic's. Check out my dumps.. http://www.yenko.net/ubbthreads/images/graemlins/naughty.gif..need to have two new pipes made up this week to reconnect the exhaust.

How about a picture of the clutch return spring mounting? I have the same headers on my 68 L78 and I used the SB rod that would go to a hole on the motor mount with a spring. I was thinking of changing the location just wondering what you did? This worked very well with these headers but I couldn't find a spring that gave me the correct pedal feel. I have a spring that is way over doing it.

03-29-2010, 05:42 PM

The BB Novas had the clutch spring connected to one of the exhaust manifold studs....I would assume BB Camaros would be the same...?? Our 70 black L78 had headers on it when we got it...the prior owner welded a small loop onto one of the header tubes in approx. the same position as the original manifold stud. Of course this is probably not an option for coated headers...but, it seemed to work fine for us. Maybe you could put some kind of band or clamp around the header tube with a spot to secure the spring http://www.yenko.net/ubbthreads/images/graemlins/hmmm.gif

03-29-2010, 06:25 PM

Mike, you did the right thing with the fuel line, we moved the line from the side to the top. If you drive the car a lot in summer heat, you run the risk of boiling the fuel and vapor locking with headers that close to the fuel line. The other issue with BB Camaros/Novas with Headers is PS. If you have factory PS, you will need to "dimple" that 2 or 3 tube to not hit the steering box. Get it cherry red with a torch and roll a large impact socket on it, usually does the trick and looks nice when done. Lastly, I removed the riveted "Hooker" emblem PRIOR to having them coated, I heared that the coating my start to flake or chip off around it if you leave it on, weather that is a valid issue or not who knows

As of now I hooked the spring to the brake line until I can fab up a clip. I figure that I will mount the clip with the brake line clamp. Look at the left side shot, you can see the spring. I will try and get you a shot of the little extension rod tommorrow if I can.

I can relate to some of those feelings Bill. Funny how things were so cut-and-dry in a young mind.

I think an air pump into an exhaust manifold can be somewhat effective since those cast iron manifolds would act like an oven. With some additional oxygen form the smog pump, those unburnt HC's could be cleaned up. I think with headers there is a significant reduction in cleaning up the HC's because you loose the oven effect.

Sounds like you had fun to day old man! You can adjust the snubbers to help the pull left or right.

I will tighten up the gap on the L/H snubber and do more of this... http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif... behind CAK tommorrow.
I will mess with the timming some too.

Just in case nobody has mentioed them already.I recently installed a set of "header buddies" on my Car.These are replacements for the stock 3 bolt collector redcers that come in the box with most headers.These are reducers that doesnt use a gasket.They have a very slight flanged crimped into the pipe,and a small{maybe 1/8") of pipe that goes into the collector on the header.They come with new 3 bolt flanges as well.I was watching Two Guys Garage one morning and they were giving them props so I decided to try them on my newest project.After I installed them,I called the guy who makes them and told him how great they are.They only cost about $40 for the pair and come in many sizes.I as very impresed.Good luck.

Hello,
I am really thinking about installing some headers on my stock 70 LS5 Chevelle. The exhaust manifolds that are on the car are not the right ones and will have to come off at some point anyway. This is a #'s matching style car that is driven just about every weekend. I am not too worried about changing gaskets if needed. Call me crazy, but I love stock appearing musclecars wih a nice sounding aftermarket exhaust along with headers. But I also like the simple and correct look of the factory exhaust manifolds. (I would have to find the correct ones of course..)
So my question is this... Who all runs headers on their mostly stock/restored cars?

I have to disagree. The headers will allow more air out of the motor which will push more air/sound through the mufflers and out the back.
As far as seat of the pants. I am thinking there will be a noticable difference. I have a fairly healthy motor that was built by Langenfelter years ago and it needs to breath more IMO.

[/ QUOTE ]The need for headers by your healthy Lingenfelter may be greater than the LS-5 in question. I was basing my "power" comment on that, from experiences in the past. Also, headers won't move any more air, just more efficiently. All exhaust leaving the exh. valve will eventually find it's way past the iron exh. manifold (where else can it go?). Also, it's known fact that a lot of sound will bleed through the thin tubes of a header, leaving less sound to make the trip to the rear of the car. I've installed a lot of headers yrs ago, when glasspacks were fairly common. It was amazing how many blown out sets got quiet after the header install. Hey, it's just all opinion, and that is mine

Groucho, I was with you on your previous posts in other threads but don't follow the points made above.

I do agree that some headers can bring noise into the car. I love the sound a of a healthy camshaft ringing the header tubes at idle.

The LS5 in question is still mild. Its got probably a little bit more than it did from the factory. But still running a Q-jet and cast intake. My fairly healthy comment meant that its not a tired old motor...
Well I am looking for a more aggressive musclecar sound. So you are saying I will have a more agressive sound in general by leaving it as is with manifolds?

[/ QUOTE ]Well, I don't know what your opinion of aggressive is. But, as I said, some sound will dissipate through the header tubes themselves. That is a sound I happen to like, but it comes more from the engine compartment area than the exhaust tips. Because of the dissipation of sound from the header tubes,less sound makes it to the tips, usually making it a bit quieter, BUT IMO better in quality. Make sense? In my 1st response, I wasn't trying to talk you out of installing headers. I was just giving you something to think about, so you didn't expect too much

I disagree that headers don't move more air. They do. Sure, eventually the same amount of air can be moved through a Mcdonalds straw, but headers will move more air that those LS5 exhaust manifolds will, given a specific window of time- say a 1/4 mile pass.

I disagree that the sound out of the back of the car will be quieter with headers. I get you theory that sound is dissapating through the headers so there won't be as much sound to make it out of the exhaust tip. I just disagree. There are several other facotrs at work here. I would think they the rougher surface of the cast iron manifold would deaden the sound more that what audibly leaks through a header, but that is just one unaddressed point.

Don't get me wrong, I am fine agreeing to disagree but you asked for some specific points.

I would say that the car seemed quieter and probably was at that particular cruising RPM.
The headers are changing the way the air is coming out. Its probably coming out a little smoother and faster. Meaning at certain RPM's maybe it is quieter than before. But maybe at higher RPM's it will actually be louder than before.

Not trying to argue what so ever. No need to get like that. Just going by my personal experiences. Plus its a interesting topic!!

Years and years ago I was heavy into the little 5.0 Mustangs. Man those things were FUN!
It was very very common to throw a set of 2 Chamber Flowmasters on these things when new. Some guys out there hated the drone at cruising RPMS of Flowmasters. Well guess what really helped that? Yip, aftermarket headers. Every time we would install aftermarket headers the drone at 2k rpm was much more tolorable. Actually the drone was still there it just went to a different RPM. But at wide open throttle and at idle the sound was louder with headers. That is my experience with changing the air flow coming out a V8. Because that is all we are talking about here is changing the air flow....

[/ QUOTE ] So on the Mustangs, as far as sound, you're comparing tube manifolds to tube headers. Prolly different than comparing tube headers to cast iron exh. manifolds. And I believe that's where this thread, and some of my opinions originated.
