PTVC with a aftermarket cam?
valve event timing has more to do with it than just lift BUT that said you are worrying over nothing. I have yet to hear of a stock shortblock motor reguardless of how wild the cam and head milling are have a problem. My heads are milled close to that much and I run a little more lift and a .026 gasket with only wonderful results.
To answer a few questions, yes, I'm worring about the valves kissing a piston. Also, my cam specs are .540/.540 232/242 109lsa.
Sorry I couldn't give a little bit more info, I was at work when I posted this thread.
BTW, I'm using regular felpro gaskets and stock milled heads.

Looks like a mean cam. Im thinking of having CompCams custom grind a cam for me with similar, but slightly different specs. This will also be going on a stock bottom end, and from what I have read the PTVC should be ok. Who did you get that cam from?

Yea I also run a bigger lift and have the heads milled and ported and run regular felpro head gaskets without a problem. Check with the machine shop or engine builder though those guys know if its ok off the top of there head.

Verdad Gallardo I would have milled less and used a gasket that was thinner. The Felpro IMO is best left to zero decked blocks with it's .039 thickness. I run the Mr. Gasket .026 after AI's chamber work and roughly a .030 cut on the heads and an asumed .025 deck this is about 11.5:1 on a stock shortblock. Cranks about 230psi and runs wonderfully.
