I just received my Crower Severe Duty Cutaway Solid Roller w/HPPO lifters and they mic between .8413" and .8421". I'm seeing as much as .0007" variance in diameter on the same lifter at different points on the lifter body. Is this normal tolerance? It seems like a big range considering lifter to lifter bore clearance should be .001-.0015.
Another interesting thing about these lifters is that I can't install them with the heads installed because of the raised tie bar and the tall lifter bores of the Bow Tie block. It's going to make servicing a nightmare.
