It’s all guess work until one takes the time to CC each chamber on a head that has a valve job done to it and or has also had new valves installed.
Just a valve job could add between 1 to close to 3 CCs to the chamber volume depending on how much the valves where sunk, then on top of that dish face valves might have been used which could add another 1.5 CCs to a chamber with the large 2.11” / 1.77” valves.

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.
