He should have no problems with the piston to valve clearance, but it is always a good thing to check anyway since there are variations in deck-height and such from the factory. Also, it is wise to degree the camshaft in to ensure the valve events lie where they are designed to (see provided cam card). If the cam is off by a degree or two and the timing set you use is off by another few degrees your pistons to valve clearance can be severely compromised!
