Setting coil bind clearance on 392 DP engine.
Check PAC spring height gage for zero. Check height add .103” retainer adapter. Subtract cup and spring shims from gross number to arrive at installed height. Subtract valve lift from installed height to get open spring height. Measure spring height at coil bind subtract open spring height and the result is clearance or interference at maximum lift. Adjust accordingly to get the number you want.
The Pac mic is the best I have ever used for accuracy and repeatability.
