I was wondering if some non P gt40 heads would work alright with a Edelbrock RPM intake (not the rpm II.) Not sure if the intake would be too much for the heads or not. If I could run mid-high 12s with those heads and intake, a good cam that doesn't require flycutting of the pistons, 3.73 gears, your other bolt ons, and some basic traction mods like subframes, control arms, and tires. Would this be a good, feasible combo? Or would I be a hell of a lot better off buying some aluminum heads?
