I also tried adjusting w/ the engine running w/ limited success. I can get all the rockers quiet but the performance doesn't seem as good. By this I mean the car doesn't accelerate as fast and seems to surge. When I did the adjustment I would pick a rocker and loosen it until it rattled and then tightened it until it became quiet....but that's as far as I could go on all of them. I could get them where I could actually feel them get to the point where they were snug but I could not get them the additional 1/4 turn that is required after you get the rocker quiet. .

Do You have poly-locks on there, or do you just have adjustings nuts? If you have poly-locks do you understand how they work?
What you stated above(I could get them to where they were quiet but could not get them the other quarter or half turm) sounds like the adjustment screw on the poly-lock is bottoming out. Thats why I ask if you understood how a poly-lock works.

Once you get a valve to the point it has just stopped clicking, it is going to idle rough for a few seconds when you go the other have turm . Thats OK. It will clear up as soon as the lifter builds back up. Just dont let the engine cut off.

Next question, Are you absolutely sure thats a hydraulic cam????
If you have a solid lifter cam and solid lifters you are going to ruin some valves trying to adjust them like hydraulic lifters.

Small block chevy valves are the easiest in the world to adjust if they are hydraulic. It should only take a half hour or so.

I applaude Denny for the help he has given you. Denny , You have a lot of patience.
