IMHO: The rev limiter won't have any impact on stud breakage. The flexing force studs will be essentially the same each cycle at all RPM's and that will fatigue a weak stud regardless. Individual stud weakness is your issue.
FWIW Just a word of caution when mulling over all of this: You can't equate stud strength and durability with that of the stock Magnum pedestal setup. The way the forces work is different in regards to the strain within the parts, and the pedestal setup is superior for strength and fatigue issues. No wonder the stock Magnum rockers are what tend to break in that setup.
