They were saying to set them up with .002 - .004 lash. I am not positive on the procedure to do this but it is imperative that you get this right! #1 reason I do not run those lifters. I'd get someone that knows what they are doing to set them up for you. Do not torque them down like stock lifters though.

ok..calm down. Yet again we need to discuss this. DO NOT confuse lash with preload. This is apples and oranges, we are talking about two completely different things. Lash is slack in the system, preload is just that..pre..loading the system. The pro mag lifters require .002"-.004" preload HOT..not cold. I would probably put .008"-.010" preload when cold. Zamboxl..you have a Pm.

After you take the slack out of the system(lash) you would give the ratchet about 1/16 of a turn on an adjustable rocker. If you still have a stock rocker, pushrod length and shims are the only ways to achieve the preload required. Comp makes pushrods for the LS-1 in .025" increments.

Ok guys,
1- the 850-16 CC lifters will handle any lobe and lifts up to .600 very comfortably, so 875-16 CC "R" lifters are not needed.
2- CC recomends that adjustable rockers are used with Comp "R" lifters. (pro-magnums) so do not use them with non adjustable rockers, "search and you'll read why"
3- TR p-rods are fine and I believe cheaper.
