I ask how long, because it will take me awhile to get the blower off for right-bank access after I warm the motor up.

How long is "a while" ? Mine has been noisy since the beginning, and I am ready to adjust them. I have type r pro rollers and the engine builder told me he set them at 1/2 to 3/4 turns after zero, then I read on Comp Cams and then here zero lash.

With comp Rs you stop at zero lash. With the OEMs people go an extra 1/2 to 3/4 turn. As your tightening the polylock you must use the sensitivity in your fingertip to "feel" the exact moment the rocker snugs up against the pushrod which then becomes snug against the lifter. Your rotating the pushrod back and forth as you turn the polylock to "feel" when this happens. This is when you STOP turning. If you continue to turn the "feel" will be just a little bit different. You will "feel" the lifter spring begin to compress if it is not pumped up(a pumped up lifter will have more resistance to the pushrod as you slowly turn the polylock). If you "feel" this subtle change in resistance as you turn the polylock you've gone to far if you're using Rs. I hope this explaination helps because this is the type of thing that is better done hands on rather than reading about it.
