On a stock LS1 how much have people been able to mill the heads and run cams like (or similar to) the F14? (232*/234* .598"/.598" assuming stock gasket .054")

I'm looking at ~.061" equivelant if I try .040" gaskets with 5.3 heads milled .007" (.030"+.007"+.024")

Also, what is the factory P to V clearance?

I know it's the same question another way, but right now I've got time to answer questions prior to commiting to tons of labor.

 

TSP ran a torquer 2 with heads milled .015 but i think thats stretching it. I dont think youre gonna fit without crossing the line into the danger zone.

IIRC, stock p to v is somewhere around .160 / .180. Idealy, you want to keep it above .100. The only real way to be certain is to measure. Calculations simply arent acurate.
