It depends on your valve reliefs and what type of head used.

0.100" at any point is safe.

clearance

.080" intake / .100" exhaust on a steel rod engine with normal piston to wall clearance. If you have excessive piston to wall clearance the piston will "rock" in the bore a reduce the p/v clearance. If you can be 100 percent positive that the engine will never go over 6500 then you can reduce those numbers by .015" each......

If you are close make sure you check your clearance in running condition... Do not use the light checker springs....
