A cylinder head bought on Ebay a while ago, turns out to have a couple of issues after cleaning and bead blasting of old grit and paint.
Two of the rocker box bolt bosses have been welded up, and not by the best welder out there. The rocker boxes may sit tight, if I get threads in the holes, and maybe I can get the oil to stay put inside by using some epoxy/JB weld on the gasket surfaces before putting on the gaskets. But what worries me a bit, is a couple of vertical cracks that are present in both the nearby head bolt bosses. I could grind out a fillet on top of the cracks, just on the bolt landing, and fill it up with weld, to lock the crack from further expanding. What would you do?
