Actually, I did it both ways since I was already fooling around with it. In my case, it didn't really matter much, since I had about .150" inch clearance. I think I actually may have hit coil bind (even with those weak checking springs) before I was able to touch the piston with the valve. The modeling clay looked like about .150" more or less as measured with calipers after 2 full crank revolutions. Still, I was happy that I had done everything possible to know for sure that I wasn't going to smack my valves againt the piston the first time I really put the engine to a 6000 rpm 1/4 mile test.
