How is the clearance with a MS3 cam and CNC ported 243 heads on a 06 GTO. Will I run into any problems?

You cant mill the heads without flycutting the pistons.

not that its a terrible cam but why ? its a dated cam and there is far better out there that produce better power and trq . u have a seni heavy car and that cam will be soggy down low esp gettin that car moving . u really need to wind that cam up to make its power. if your going in ya may as well use a better cam in my oppinion man .
