Hydraulic Roller Lifters.

[Methuselah]

Id like to get a new set. What brand/part number have you rebuilders gotten? What diameter am I looking for? Any other considerations...I have no clue?

The stock GM hydraulic roller lifters work fine. I've also used the Crane hydraulic rollers that are a direct replacement for stockers.
