Roller Lifters vs. Schubeck style lifters

Thanks Rob I had heard that the ceramic puck will get shattered if there's any float. The springs that my cam calls for are only 115# at the seat and 336# open. With a roller I'm sure I'll have to run higher spring pressures too. Don't think that shimming the springs will be enough to bring the pressure up in my springs to accommodate the schubecks or roller lifters. I think I need around 175-200 for the Schubecks

Still deciding. I may call ya later Rob
