That casting is the 2bbl 400 head which was rated at 265 Hp .
The head is about 90 CCs and on a 400 gave a actual like 8.4 comp. Bolted to a stock 421 you end up with a compression in the neighborhood of 8.7. Flow wise they are better then the stock 421 heads. These heads are 1.96” intake and 1.66” exh with pressed in rocker studs. On a 421 you would need the 400 length push rods . With stock 421 pistons you could not run and more then about .450” lift depending on the cam duration.

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.
