I have bought some heads a while back and they have been ported, had cc work and had bigger valves installed. Got a great deal @ $600. They are the aluminum earlier 93-94 I believe 346 part number. The numbers have been ground out of the heads and there is a stamping of,,, G C P then they are dated 2-2-03.

Does anybody have any clue who the GCP is?

They came from the eastern U.S. is what I was told.
