Piston to Valve clearance

Did lots of searching and seems like lots of opinions.

Is 0.060" enough clearance for I&E?
I'm running 60# springs, mild cam and 3k gsk.

If not I'll get 0.010" over headgasket tomorrow.

Thanks in advance.

You should be fine at that.

Out of curiosity, what is the minimum you feel comfortable with?

I agree with .040, but got away with .032 when I put a 188/220 in my original engine. Never spun it much higher than 3800 though.

Lucky for you guys. I have .027 on my race motor because Of a machining problem. We will see how bad they are in a few months. So far it's making power
