I HATE HEADERS!

Most should clear the steering box.... most (I had to dimple a set once on a 68 Camaro that didn't come pre-dimpled.) also most are going to give you plug wire clearance problems on the passenger side. That's why I suggested the other alternative (see link above).

I would be done with the blue coupe by now if it were not for all the problems I've had which were brought on by installing headers. FWIW, it that 302 has a std. 4-speed behind it, you're going to have to modify or relocated the clutch return spring.
