Some good answers here. The idea of "pumping lifters up" prior to installation went away many years ago. The reasons sited in the quote from Comp is exactly right. I used to have a SnapOn "lifter pump" (looked like a pair of pliers with odd "ends"). Sold it in 1981... We actually srtarted setting "stem height" and counting the number of threads exposed above the nut, not unlike the "non-adjustable" Fords, Dodges, Pontiacs, etc. Makes for a much "nicer" engine when you don't have to "open" it again (valve covers).

The GM EOS idea is good. We've been doing it with STP for years. We use a noly-graphite "paste" on the lifter pottoms and rod bearings, "Mellube" or FM assembly lube on the mains and cam bearings, and 30 ND on the rings and pistons.

As long as it says "assembly lube" somewhere, you're usually okay. No white lithium, PLEASE! (it dosn't "blend" with engine oil)
