Default noisy roller rockers, what is considered too noisy?

I heard roller rockers can be noisy. Why is this? What is considered too noisy? I have ford motorsports adjustable roller rockers that i have adjusted 3 times now.. All of my lifters seemed to be pumped up and don't move when I push on the pushrod, could I still have a couple that are bleeding down. The noise seems to fade in and out and is more noticeable at idle. I have a mechanics stethoscope, but i am still not able to pinpoint one particular loud one. Some just tap a little louder than others. I can hear it in the car, over my 40 series flowmasters, but not over the radio. I've tried setting them at 3/4 turn past zero lash and now they are set at 1/4 past zero lash. Have new trickflow pushrods, so its not them. Car runs great and rocker can't be heard above 2 grand. Had it over 5 grand several times and everything seems fine, just that annoying valvetrain noise at idle. I'm running 10w-40 castrol syntec blend oil and my oil pressure is around 50 psi.

Default Rocker Arm alignment

My openion on noisy rocker arms is if the noise sounds even its ok ,if some rockers sound a little louder than others and the ajustment is correct there could be a chance some rocker arms are not alligned with the valve tip roller rockers have roller tips so check the top of the valves for pitting or erossion these things will make a rocker sound loud even when the rocker is ajusted correctly

You should be fine, they do make more noise than the stock arms do. A lot of guys like the extra noise.
