Re: valve to piston checking tool

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.

X2 I have one of those, too.
