If using the head as a guide, bear in mind there is a fair bit of slop so you need to locate the head to the block.I use a couple of turned down capheads, turned down so that they are the same OD as the ID
in the cyl head, obviously you need to get a couple of studs out to start with.
RPM those studs have not been out in a very long time some breakages are inevitable.
I would much favour stepped studs over Helicoils . To use Helicoils you end up with 3/8 hole so you might as well use a stepped stud, stronger and cheaper.
