Head Q on 421
Just purchased a 1966 YK 376 HP 421 complete motor w attached 400 turbo. Engine is minus factory tri power intake and trips. Engine did come with factory LB headers. My question is the 093 heads have an A stamped on front port on driver side and a C stamped on front port of passenger side. What do these these stamping mean?

More than likly the work shift the head was cast/made on.
the good news is that there is only one chamber size for the 093 head, unlike the latter heads so you can scratch off that worry.

Thanks for the input Steve. I was wondering if that was it myself.

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.
