Lots of guys do them without the engine running and turn the engine over by hand.
I like to set them hot and running. Back them off 1 at a time until they really rattle, then tighten them up until they just get quiet, then another 1/8 to 1/4 turn..

if you do it tim's way, make sure you get a thin walled socket. it's not too bad a problem with the floppy stockers but any of the good aftermarket rockers will bind on the socket, rough on the engine. but that's the way i prefer to do it too.
of course, if you know which ones are tapping you can always just turn them down a 1/2 turn while cold until the tapping goes away or the idle roughens up.

Thanks for the help, not sure what one is ticking but i just boutght the car last fall and just getting around to working on it. I did notice that the rocker arms look stock but have rollers on the tips, are these after market or did they make stock ones with rollers? I dont know what was done with the car so I am going through everything i can and making sure it is correct. So I want to readjust all eight rockers. Thanks again for the help.

Those are aftermarket roller/rockers. If a good quality brand, they should be just fine. Just follow the procedure for setting the lifters (assuming they are hydraulics). Take your time...and do one at a time. In short order, you will find which ones are 'ticking' and either resolve it or find there is another problem. If you haven't got enough adjustment for one or two lifters, it could be that your pushrods are just a bit too short.

I like to do it with engine running and warm.start backing (SLOWLY) off on one till it rattles..its easy to tell and hear,you will know when its enough. Slowl turn it back down till rattle stops, about 1 flat at a time,then waiting a few seconds for them to adjust.Once the rattle is gone,I go 1/2 turn more( SLOWLY). The book, I think, calls for one full turn but hotrodders have found 1/2 much better for them. Thats how we did it in the 60s and 70s,still works good today.( jeeze, I just looked where your from.I am a Schneider driver and pass thru there)

I see you in that Huey. I used to catch rides with you guys in Nam. You always scared the s__t out of me. When I hear the popping sound from the engines of those things, I can close my eyes and smell that place.

That's how I do it, only I use oil clips to keep the oil from shooting everywhere. Not all motors need them though, depends on your idle oil pressure. I also have an old valve cover that I cut the top out of that keeps oil from running out of the head onto the motor.
