I used a set of these heads on my '67 GTO with flat top forged pistons .030 over. Ended up with about 9.3 CR. The heads cc'd at 87 and I upgraded to screw in studs. I can now run 91 octane fuel and it runs fine with an 068 cam and stock intake and exhaust. Been on the engine about 12 years or so and a lot of miles.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
