Need Feedback on MRL Roller Lifters!

I have a set in my SB and a set in the BB. Haven't ran either engine yet. They did fit OK in both applications. Had to open up some areas in the BB but I have 3/8" pushrods and am using the .800 offset lifters in a new combo (block and heads are both new). Went with non-oilthrough pushrods and lubricate the top of the pushrods via the lifters.
