Definitely use 72cc aluminum heads on a 428.
The iron intake will be more than fine, an excellent choice that also happens to fit your needs.

I sent a note over to Butler with couple of questions about parts and my plans for the 428 and they replied telling me that the 72cc E-heads on a 428 would require 93 octane gas and recommended going with the 87cc head. 93 octane is readily available here in NJ, I thought I would only need the 87cc heads f I stroked the 428 (or the 400).

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.
