Guys thanks for all your help on both threads. I took a small rod and put it along side the pushrod and set a dial indicator on top. I then set the pushrod at zero backlash. I tightened the rocker nut 1/4 turn and waited. It took about 90 seconds and the indicator read .009. I then added another 1/4 turn and in less than 60 seconds it read .020. So, I have hydraulic lifters. Unfortunately #1 exhaust and #5 intake lifters I can rock the rocker back and compress the lifter maybe .060. Which is why I started this campaign, the valve train isw making noise cold or hot. Again thanks for the help.
