The needle bearing deal is mostly because of "sloppy" valvetrain. Lifters bouncing around in the lifter bores and etc. I don't think the spring pressures are whats causing lifter failures.

I agree with Marv on the Morel type lifter.

You can call Chris Straub and tell him I sent you if you want. He sells a TON of lifters each year and ask his advice. 1-423-391-7771
