Jeep Strokers

Before I start Thanks for the reponses on the Yella Terra roller rockers.
Now for the pushrods. I took .025 off the head and deck the block .030.
My machinist ordered what he thought was .040 under but the are actually .150 shorter.
Just placing a orignal one in there and taking zero lash on the pushrod I can measure.051
between the rocker spacer and the boss on the head. I believe this would mean .051 preload on the lifter.
I thought I needed to be between .025 and .060. Any thoughts and ideas on a different way to measure preload
to order right length pushrods.
Thanks

One option is use an adjustable checking pushrod to determine the length you need. The other option is install the rocked until 0 lash. Using the head's valve cover gasket surface and a straight edge score a mark in a push rod. Now, tighten the rocker bolt down to spec and score a new mark (if the lifters are filled you may want to wait a little so it bleeds down first). Remove push rod and measure distance between the two marks. That is your preload.

I went with the 1/2 to 1 full turn rule. Take up the rocker bolt until its just touching the pushrod and valve, from this point it should take between 1/2 to 1 full turn to achieve specified torque. All of mine landed near 3/4 of a turn with stock push rods.
