So I measured the copper head gasket that was in the motor this cam came out of and it was 0.100" total thickness. The old stock head gasket out of my stock motor measure 0.065" (sound correct?) Leads me to believe ptvc was an issue.

My piston protrusion on #1 is 0.028". Couple that with 0.041" valve face depth, I don't think this cam will "drop in" with appropriate ptvc.

I'm thinking about getting my stock cam polished and selling the high lift Enterprise cam to somebody who wants/needs an aggressive cam.
