Has anybody had issues with valves kissing piston tops (high lift cams)? What were the valve to piston clearances? RPM's? Minimum recommended clearances (intake and exhaust)?

Yes. But was an over rev situation. I design around .060 intake, .100 exhaust. If the driver is sketchy, now I?ll increase that. [emoji5]

Should have clarified that the whole system must be accounted for.... cam accel/decel rates must be matched to the spring force, with at least 20% margin of safety.
