I didn't want to drive the hour to work and then an hour back to get my dial indicator, remove the valve springs and install the checking springs so I thought I'd just stack feeler gauges between the rocker and valve tip and see if the engine stills turns over with no binding at the critical points from 15* BTDC to 15* ATDC. And it does. I have .098 under the exhaust and .087 under the intake. I think I have enough clearance.
