# 48 heads
i bought a 1970 ram air engine that had been removed from a 24k mile 70 t/a years ago due to a spun rod bearing . It had a set of #48 heads that were both date coded H-20-8. My question is would these be very late 68 heads or very early 69 heads? I thought yearly change over was either August or Sept.

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.
