Head bolts--------- 22 ft lbs.
Intake upper------ 18 ft lbs.
Intake lower------- 10 ft lbs. Tighten vertical bolts first, the diagonal bolts, failure to do this will result in an oil leak.
As far as the rocker arm bolts, they have to be adjusted with the valves closed, tighten down just enough to turn the push rods with your fingers with slight tension.
This is out of a Technical Specifications Manual.

14 ft/lbs first pass on all then an additional 30 degrees for all on final pass ..by the way 1 bolt flat to the next bolt flat is 60 degrees so all nuts get half a bolt flat final torque if ya wanna throw caution to the wind torque it to 16 ft lbs and be done with it. lol these specs are from gm ok. good luck and ps the intake pushrods are shorter than the exhaust pushrods and there is no clearance if you get them in wrong an apprentice found this out 3 years ago and a lot of people saw what happens lol..good luck
