i need help finding out how much valve clearence to piston i have.

i have a 40 over 360 with Kieth Black pistons..#107

i have crane gold rockers.. 1.5 to one..
i want to put a .600 lift roller cam in it..and dont know if i have
enough piston to valve clearence...or is the cut out in the piston big
enough....?
