Now we can install the Crane (or your stock) rocker arms on the studs. In my case, its a stock pressed in stud, but many of you will have an ARP screwed in stud in place of the stock studs. If your going with a big camshaft that needs high spring pressures you stand a chance of pushing a stock stud out of the head. You need to use a screwed in stud for aggressive spring pressures.

Make sure you put each rocker on each stud, make sure if you have nuts like these that the inner lock nut is turned back towards the top of the outer nut so that you can adjust the outer nut on the stud before the inner nut interferes.

The rule is to rotate the engine over and watch the #1 intake rocker go open and then close, now go to the TDC or 0 degree mark on the dampener to make sure you are on the cams base circle, this will allow you to adjust both the intake and exhaust valve/rocker on that particular cylinder.

If you are in a hurry, you can do the job on all 8 cylinders in 1 crank revolution by follwing the order of the cylinder firing.

You can also adjust number 2,5,and 7 intake valves and 3,4,and 8 exhaust valves while doing the number one cylinder. Once these are done rotate the motor clockwise exactly one turn. You can now adjust number 3,4,6,and 8 intake valves as well as number 2,5,6, and 7 exhaust valves. Once these are done the valve adjustment is complete.

Replace both valve covers using new gaskets. Take special care to thoroughly clean gasket surfaces and do not over tighten cover bolts.
