I was refering to the "two sides to every story" part................
Its still two sides if Customer is claiming the lifters failed because of Builders spring choice and Builder says Customer provided used lifters of unknown history that may have already been hammered on before being put into use.
I dont see how a lifter link bar can fail because of incorrect springs.
I would think that if the lifter was getting into the block too far and the link bars were hitting the block then Ryan would have machined the lifter bores to clear the link bars.
I cant make it work in my head how the springs caused a failed lifter from them hitting....
Lifter link bar did not fail. The lifter roler (wheel) fractured from bouncing on the cam lobe. The bouncing happens from spring surge when the valvetrain is incorrectly set-up. There was even evidence of that the exhaust valves contacted the pistons. I am certain this would have happened even if the lifters were new.
