Always knew the heads were incorrect on my 69 GTO and thought for years they read 96 (from a 71 GTO) Got the old ones removed the other day and I have a correct date coded set of #16's going on. Now that they are off the motor I finally can read the code up close and they read #94. Any ideas what these are from? Perhaps a big Pontiac? Are they worth anything?

To the best of my knowledge, 94 heads are from a 71' 250 hp 350 engine. I think this was a 2 BBL engine, so the heads would be low compression and small valves. Just my guess though. If this is the case, the value of these heads would be slight as would be demand. Do you have a date code on them?

Date codes are L170 AND B031, so they are 1971.

Mr. G is right, they should have come from a '71 350. I'm working on a set of #94's right now for my 428. They were right at 87cc's on the chambers I measured so they are a very good size for a 428 or 455. Mine have been converted to the larger valves and screw in studs. The small valve #15 heads with similar 87cc chambers are starting to become more widely used for the same reason. They do have some value as very few Pontiac heads have that chamber size. Rick

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.
