Oil pump/stud interferance

A couple of engines ago I took the time to cut the stud down, used a 12 point nut (also cut down) and clearance the pump with a grinder....it worked, but there was not a lot of the nut left to torque properly (was doable, but a pain). The last engine that I built for my car I just picked up a single ARP bolt for that hole (studs everywhere else)....WAY easier to deal with than my other setup.
