What are the stock rocker torque specs ? is it ok to reuse rocker arm bolts ? are the stock Ls2 rocker arms ok to reused on stage 3 patriot heads with a 231/237, 589/595 on a 114 cam ?

How do i find out the Valve lash when tightening the rocker arms ? WHAT SHOULD IT BE ?

Are the stock Lifter Trays ok to Reuse also with almost 600 lift cam ?

i am reusing the stock lifters , they should be fine shouldnt they ?

The rocker arms bolts should be OK to reuse assuming the threads are intact. Torque to about 22ft-lbs with a good lube like ARP or CMD.

With a hydraulic lifter valvetrain, you usually set a preload, not a lash setting. You tighten the rocker bolt until there is no lash, and then tighten 1/4-1 full turn. If it takes more than 1 turn or less than 1/4 turn, you need a different length pushrod.

Stock trays are usually OK to use, but new ones are cheap and it's kinda like "why not?" Same with reusing lifters. New GM lifters are like $200. If you re use them, inspect them very, very, VERY carefully and disassemble to clean if you can.

Hope that helps.
