This website will show the tightening pattern and the valve lash for your engine.
I oil the threads and under the tops of the heads before installing before installing the head bolts to allow the bolts to stretch easily under the torque wrench. Tighten them in proper sequence to 30, 60, then 90 pounds. Then, one at a time using the same sequence, back them off 1/4 turn and then torque them down to 100 pounds.
If you want to pre-set the lash cold, set the intake to .008 and the exhaust to .021. That will get you real close to the hot specs and you can fine tune when you get the engine hot. I find it easier doing it this way because it saves time spent reaching over the top of a very hot engine! Most of the time, you'll find that at least half of the valves will not need any adjustment when hot if you pre-set them cold.
