Thanks guys. I recall there being discussion about the 670 heads (I think). The letter code would make sense to possibly mean a different valve spring on the head or possibly chamber size. I didn't think the letter code was a Z though.
These heads are 1968. Thanks for the link. I wasn't having luck finding that. |

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.
