What is minimum Piston to Valve Clearance?

[krazykuda]

Hi guys. Putting a 360 together and wondering what is the minimum piston to valve clearance?

My cam has over .500 lift and I need to know if I have the proper clearance. We have .250 " intake and .185" exhaust. I think that is good, but I need to know what the minimum is for my own piece of mind.
