60539 would be the correct comparison for the bare heads. 60589, are the older style chamber that doesn’t need cnc’d but just polished. But they actually cost more now than the Cnc heart shape chamber. The cnc e’s are 60539 at 72 cc. Which are 870.50 through summit.

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.
