    are these supposed to make noise? also are factory push rods okay to use with these? I've adjusted multiple times getting to 0 lash then half a turn and it's still ticking

    Asked by: MaroonZ71Goon
    Proform 778-66922 are not supposed to be noisy, i would verify proper oil flow and check the lifters. Verify valve train geometry. you are setting lash properly but the only way to know if the pushrods are of proper length is to measure.
