Not Ranked
Ron,
The GT40P heads have a different spark plug location, so they do require a specific header or some hammer work. I'm not totally sure, but I believe 64CC is right for the chamber volume
As far as the manifold goes, I would have probably used the RPM, but my car doesn't have a hood scoop so I opted for the Performer, which is a little lower. I expect the performance difference would just be a shift upward in the power band and perhaps a little extra HP. I'd rather have the grunt at lower RPM's and this combo gave 390 FT/LB plus from 2500 to 4400 RPM.
