9.4 to 1 compression is LOW for one of these engines, especially with aftermarket aluminum heads.
Compression is power (torque) and moving up from 9.4 to 10.4 or so allows for 10 degrees more camshaft with zero negatives anyplace, and it will operated just fine with the same octane fuel.....FWIW......

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.
