well id suggest u check it. i have tfs heads milled to 60cc (i believe 60 or 61 is stock ptv clearance) w/ .045 gaskets and i pulled the drivers head and both 1 and 3 had a nice little half moon in them. ive hit the limiter once since these heads have been on and it was very brief. the valves seem to be ok and are still sealing but if u think ur cutting it close measure the ****!

TFS heads? What are they such as LS6, 5.3's?

they're trick flow specialties, not stock castings
