I went though this with my 1969 Camaro with the 454 and 540. I ran Dougs short 1.75 headers first and I was very impressed with quality but the tube interfered with the power steering box so I had to dimple it. I went to Hooker 2.0 super comps the next time and the fit was better. I installed the headers in the car with the motor in place and it was more work than expected. I would recommend pulling the motor out of the car and placing the motor back in after you put the headers in position. Then you can replace the motor mounts and stands at the same time. I went to urethane mounts and gained a little more clearance in place of the original style mounts. I also ended up replacing the exhaust system with a 3 inch system to work with the bigger headers because I was not happy with the transition from the 3.5 collector to the 2.5 exhaust pipes.
