Whats the duration on the cam? Just curious. Flat top pistons should give you no clearence problems. But with open chambered heads you might not get the compression you need to run that cam. Any Domed piston should have valve reliefs, but check the manufacturers specs. And do a clearence check upon assembly to make sure. You know clay on top of the piston turn the engine by hand, tear it down and see how thinck the clay is. Yeah it's a pain in the butt. It is better thean turning your new motor into a boat anchor! lol
