The ones on the 499 are around .900 lift on both sides with 1.7 rockers. They didn't run out until well into the 8000's, if not more. I've seen 9300 and maybe more by mistake.

I don't know if these are MC, PSO, or what. I will try to get some clarification from Adger Smith when the heads get back to him to be freshened up. He built them originally when he built the engine for the Hardesty's.



This will be a 604 with 1.75 in 1.7 ex 55mm roller cam.
