Default Early heads on later block

I picked up a ‘70 400 engine with a Weiand 671 blower on Weiand WP 671 manifold and ‘59 531395 heads. It was supposedly fresh and ready to run but I saw enough mismatched bolts to warrant a tear down. It looks like there was some serious porting done on these heads with the intakes measuring 1.23 x 2.22. Looks like some chamber grinding done, I’ll have to check CCs and dished pistons. It has oil through push rods and aftermarket roller rockers. I’m looking for information on what else I need to check and how to set up cooling. Is this even a good idea to go forward with? Building a ‘56 Chieftain gasser that this would look awesome in but I also want some reliability.

About Us

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.
