Rocker arm question
I have some new trunions and bushings on the way since my old ones wore out on me. So I have some questions about install. First of all is there a difference between rockers? Intake and exhaust side? Also, I see that the torque is 22ft lbs. Should I make sure the cylinder is at TDC before torquing? Or will the spring and lifter absorb the torque down to spec? All input is appreciated.

I don't believe the rockers are offset like the LS3 was so no it shouldn't matter. And no you don't have to torque them down @ TDC. You can put them all on and torque them to 22ft lbs. Some say you should as good practice but I have done it both ways and never seen any difference.

Thank you! I hate that I even have to crack the beast open, but after a tip that the bushings I had go bad I had to check, and I am glad I did.
