    have to look in the gm power book but the zz502 and HO had re work valving in the lifter never look at them that close and side by side. but i built them with stock lifters and the HO s i am not sure if you going to see anything from the out side of the lifter. if your looking to run lift past the zz502 cam you want a better lifter then stock or HO ones. at full lift with big cam can expose the lifter oiling hole and will make lifter bleed down
