the pro magnum lifters are the "R" series. The high energy is a stock OEM replacement type. The "R" series requires only .002"-.004" preload hot, so I would do about .008"-.010" cold. Lash and preload is not the same thing. Don't confuse the two..it will get you into some trouble.

The R lifters have a heavy duty locking retainer that holds it together and has nicer rollers on them. Other than that the ones that I am looking at they are identical(cc850 vs cc875).

I went with the stock OEM replacement, the 850's as I retained the stock rockers and plan on using a mild cam.
Don't forget the pushrods which are probably the weakest link in the LS1/6 valvetrain, Comp makes the excellant Hi Tech's which are available in a variety of lengths to suit your needs. Comp also has a handy pushrod length checker which is well worth buying.
good luck!

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.
