Easy, put your finger on the rocker arm. You'll feel it. Tighten the ones that are clicking until they shut up and then do them one at a time. Did you decide how much past zero lash you're going to go?

I never liked doing it that way. I always use the comp cams method and it always works great. Use steps 7-8

went ahead and did the engine running method.
it was pretty easy, just was a bit intimidating at first. especially since it was smoking like a **** from the oil dripping onto the headers.

You should ALWAYS use a splatter shield when tightening in this method!
Beer case cardboard cut into strips and shoved into the head in a manor that allows it to drain back AND keeps the oil off the exhaust .. Works well ,Unless you want a fire and or a stupid smoky mess.
On a side note worthy of mentioning, a automotive stethoscope is a good CHEAP tool to use when doing this to single out one rocker from all the others..
So simple it is stupid

To me this is the best way.EO IC method, Exhaust Opening/Intake Closing. Get yourself a handheld starter switch to make it even easier.

This is the way I did it on the engine stand. My question is how often do you guys check your rockers? I thought the whole purpose of the set screw was to make sure they don't back out?

I've done it both ways and I prefer the engine running method unless the car has pretty loud exhaust. I even made a shroud out of an old SBC valve cover with the middle cut out. If your having a hard time hearing it you could try a mechanics stethoscope or a screw driver. I have only readjusted mine once since I did the LS7 lifter swap over a year ago.

Same.

I always hear about people and their rockers backing off though, so I use the 1/16th turn-set-screw-poly-lock-thingy method. I haven't adjusted my rockers in 2 and a half years and they haven't backed off yet!

I get the lifter pre-load set, then torque the set screws in the poly locks to 22 ft/lbs.
