Better read the Comp literature, the R's require adjustable rockers and 0.002"-0.004" of preload. I would look elsewhere for lifters.

Comp recommends adjustable rockers with those because they require a very narrow range of workable preload specs.

Either the GM "LS7" replacement lifters or the standard Comp non-R lifters. Always measure for pushrod length regardless of which.

The R's have been mentioned many times, and not recommended.
