As my father-in-law would say, "How do it know?"
In other words, what's the difference between a head bolt head turning
and a nut turning? Granted the bolt itself isn't turning when you use a
stud but that doesn't really touch the head, just go through it. So why
would they make a difference to the longevity of the head?
