[big gear head]

I've never installed headers from the top. I actually didn't know that it could be done. I know that my Camaro is different from your Chevelle, but I have to remove the oil filter before I can get mine in on the driver's side. The clutch Z bar also has to be removed, which is probably the hardest part because it goes through the header tubes. I remove the carburetor and put a lift plate on the intake manifold and use my engine hoist to lift the engine. This does take 2 people.
