356-T6 alloy?
Are coolant passages pretty much a copy of RAV?

Yes, thank you, and yes 356-T6. We improved the water jackets significantly. As we all know the RA-V has a better valve order for eliminating Siamese exhaust port problems with respect to that center head gasket problem, and we also got significantly improved water flow to the exhaust side of the head. RA-V's were way better than traditional Pontiacs to start. ;-)
These heads will be available in with or without water. How many no water jacket guys out there?
