the correct way to install the rocker arms varies alot, but the gist of it is you have to preload the hydraulic lifters. When I put mine in I tightend the rocker nut until I couldnt turn the pushrod with my fingertips then added a 1/4 of a turn. After that all you need to do put the set screw in with an allen wrench and you're done. I didnt torque the set screw in (the damn things didnt come with any instructions-thanks, Comp Cams!) so I put them in snug but not so tight as I would not be able to get them out again. Hope that helps some.

Regardless of the brand, here are some instructions for installing Stud mounted roller rockers: Crane Cams

i found this link and used it when i did my rockers...
Stud mounted adjustment:
"1. Remove the valve covers, and pick a cylinder you are going to set the pre-load on. Only do one cylinder at a time.
2. Rotate the engine in its normal direction of rotation (clockwise) and watch the exhaust valve on that particular cylinder. When the exhaust valve begins to open, stop and adjust that cylinder's intake rocker arm.
3. To adjust, back off the intake rocker arm adjusting nut and remove any tension from the push rod. Wait a minute or two for that hydraulic lifter to return to a neutral position. The spring inside the lifter will move the push rod seat up against the retaining lock, if you give it time to do so.
4. Twist the intake push rod with your fingers while tightening down the rocker arm. When you feel a slight resistance to the turning of the push rod, you are at "Zero Lash". Turn the adjusting nut down one half to three-quarters of a turn from that point for street applications. Use 1/8 to 1/4 turn for race applications. Lock the adjuster into position. The intake is now adjusted properly.
5. Continue to turn the engine, watching that same intake valve/rocker you just set. It will go to full open and then begin to close. When it is almost closed, stop and adjust the exhaust rocker arm on that particular cylinder. Loosen the exhaust rocker arm and follow the same procedure described before in steps 3 and 4 to adjust this rocker arm.
6. Both valves on this cylinder are now adjusted, and you can move on to your next cylinder and follow the same procedure again.
There may be some initial valvetrain noise when the engine is first fired up but once oil pressure has stabilized and the engine heats up, it should quiet right down to a normal level.
Remember that some racier camshafts will have a mechanical sound to them and will not be a silent as factory units."

It's not a bad idea to put some oil on the rockers and the tip before you start the car.
A cheap way to prime the motor without removing the distributor is to pull the coil wire and crank the motor for about 10 seconds. This should get some oil up through the push rods without "starting dry." It's not the best way to do it, but it will help a little.
