Is the broken rocker boss the main reason you want a new head?

You might take it to a local machine shop and see if there is enough meat (iron) left so that they could mill the rocker bosses down and put in screw in studs with hex shoulders (no need for guide plates). They can also mill it down more if nec. and put a washer under the stud that is the thickness of a guide plate. Watch this video and you will see what I mean.

I assume all the rocker bosses were pinned, and all at risk for breakage.
