The rocker shaft is held by studs. I always have mine helicoiled so they
don't pull outta the head - I read too many horror stories lately.
What I have done on really mangled threads is have them completely welded
and then retapped to accept helicoils. This has been a recurrent theme on
several heads I have/had. Especially the thermostat threads.

bolts on the top which secure the rocker mechanism were removed and then
brass inserts were pressed into the head; I assume the threads were stripped
or something? Upon tightening, and probably over tightening, one became
stripped.
