so since I have been in training all week last night was the first day I got to touch the car.

I pulled the valve covers looking for anything obvious and still came up dry.

pulled all the plugs and and rockers and decided to triple check pushrod at TDC.

checked every cylinder on the driver side head all at TDC. results were all the same!

intake 10.5 turns = 7.375 @ .050" preload
exhaust 10 turns =7.350 @ .050" preload

The 7.4 according to this is giving me
.075" intake
.100" exhaust

I have a 7.4 which I thought would be on but maybe due to the high lift its causing issues and possibly bottoming out the lifter.

A 7.350 with give me .025" preload intake and .050 exhaust. Just need a few peoples insight on this subject with a can with this high lift
