Larry, do you also have a tool (I think mine came from Moroso, about 20 years ago) that holds a dial indicator, sets on the gasket surface of the head, has an Allen bolt with the Allen head ground to fit in a head bolt hole to locate it. Put the ground bolt head in the short head bolt hole in the head, indicator stem touches the face of the valve head. Measures the distance from the head gasket surface to the face of the valve. I use it to verify my valve hight are all equal. Intake all the same, exhausts all the same. If you used one (you may have) to get that piece of a head there to verify they measure the same as your race heads. Then, that would be an accurate clearance checker.
After that, I measure valve drop to the piston @ TDC on all valves. I have caught piston valve pockets off over .010". I'm kinda anal about all my clearances. I can't afford to be knocking heads off valves. Hell, I can't really afford to be doing this anyway. I need to quit. Getting too old.
