You seemed to think Russ Gee may have been involved with your heads. I suggested, it seems more likely RUSS racing heads were involved with your heads. They even spell RUSS the same way it's stamped on your heads.

That is good info that you found on Russ Barfield.👍I need to look up more info maybe some one out there has a known set ported by him with those similar stamping.The Russ Gee reference was just a another possibility since he was involved with engine development etc.If another set of heads surface that would answer the question.If you look at the specs on the Felpro 1233 gasket there is only .02 differences in the height.The Felpro 1233 is actually talller than the RA IV port.
