Don't spend too much money until you have your 403 heads checked for cracks. I haven't seen any in YEARS that weren't cracked badly.

Fyi...the speedpro / trw forged are gone. Discontinued. That leaves cast junk pistons or the KB 6cc pistons. There is always custom.

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.
