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.
