I used ARP studs on my rebuild. I carefully measured the stud height to arrive at a height where the 12 point nut was in the middle of the available thread. I found that the hieght was correct when measuring to the top of the thread, before the taper on the rounded top. I still have less than 10,000 miles on my rebuild - but I plan on checking my head nut torque during regular valve adjustments.
