Got my Cam Back from Oregon

well Im thinking if there is no play when you tighten the rockers down and that lifter cup is depressed just enough where the oil pressure will remove the lash it would work no? the lifter plunger doesnt need to be halfway etc just enough where lash is taken up with a small amount of hydraulic ajustability left for minor wear etc. now if you tighten everything down and the pushrod doesnt sit in the lifiter plunger cup or depress it then the pushrods are short. if you prime tthe oil system and its still loose etc that would indicate short pushrods also
