..i know the minimum suggested is .100... my exhaust is .085 and intake is .060..

i know the right thing to do is pull the short block apart and fly cut the pistons, but i really hate to get into the short block right now, this was supposed to be just a simple cam swap.

what do you guys think my odds are of getting away with my .060/.085 clearances. i have brand new springs in and they are 600 lbs.. so i probably wont be encountering valve float. the cam is a 4400-7200 powerband in a race-only car.

some opinions guys..? thanks.

I wouldn't. The problem will come when you advance the timing.

As long as you can control the valvetrain you will not have any issues, we've run tighter into the 7500rpm range. You could add a slightly thicker head gasket to give a little added clearance if needed. Timing will be critical, were are you checking the clearance at, the piston is closest at 10 degree before and after TDC, CHECK THERE.
