Folks,
I am preparing to decarbon the heads on my B43M but have read that some have had head bolts break during removal. While I know that there's probably no sure fire method of ensuring that the head bolts won't snap if their frozen, I would appreciate any thoughts or advice before I start turning wrenches. I've read that in some cases folks have taken their motors to machine shops when a head bolt snaps. That's great if you have a reputable machine shop nearby, but my cursory search indicates that reliable shops who have mechanics who are familiar with Onans are in short supply in my area.
Many thanks in advance for your assistance.
