any way to bench test these rollers before installing or is it a roll of the dice?



Pete I can't think of anyway to bench test something like that , you may have to disassemble , take all kinds of measurement and measure spring pressure inside the lifters ?

I wonder how much of these problems are related to roller cam spring pressure being too much for the lifters ?

I looked into putting stock magnum lifters in big blocks but it's too much money and work to be able to buy a low cost lifter lifter and what kind of spring pressure would they be good for ?
