what size push rods
I have a 93 block with gt-40x aluminum heads that have been shaved .25, i also have 1.6 roller rockers and an e cam. will stock length work? I am getting hardend push rods and guide plates but not sure if stock length will still work. thanks

RE: what size push rods
Maybe, maybe not. Lifter preload is supposed to be .020-.060, so if you were at minimum preload, like .025, then you'd be at around .050. Without knowing what your preload was before, can't really tell. Besides, if they're too long, just shim the pedestals(if they're pedestal mount). If they're stud, then check to see what the rocker manufacturer says on how to check rocker geometry/pushrod length. You might be fine with stock length, you might not
