stock PI head cc volume?
I am trying to calculate my compression ratio and plan out my rotating assembly but I know the cc volume of the heads also affects compression ratio. I just recently picked up a set of PI ported heads. Any way to tell what the CC volume of these are? thanks

If the combustion chambers have been reworked (not just the ports) you'll need to contact the shop that did the work--they should have that information.
The stock PI heads have a volume of 43.9 cm³, ±1.5 cm³, per the shop manual...
