I think if you installed the cam and crank without the timing chain, set the cam so that both valves were completely closed. Then brought the #1 to TDC and measured the piston/valve clearance with the method Fang pointed out it would be the absolute worst condition. If you have adequate clearance there you're assured you'll be ok anywhere before or after TDC.
