Is there clearance from the inside of the rocker to the locking nut in that area? Meaning - is the cast portion of the rocker hitting the nut in that area and causing a stress riser?
Is it time for a stud girdle?

That would make sense. The intake and exhaust pushrod lengths are different in those things so it could explain why only the exhaust is breaking.
Just doesn't seem like a failure would happen where they are breaking even if they were heated up too much, should be breaking down where they are loaded.
