So here's some pictures of the cam bearing cap mount that was ripped off. I cut the broken cam so I could insert it into the cam bearing to test the fit. I also clamped the cap onto the base.
Picture without the cam from the front of the engine:
Picture with the cam inserted half way viewed from the rear of the engine:

As mentioned previously I'm thinking a longer stud could be bored and tapped into the head itself (below the broken off piece where there's about 1" of cast aluminum), then when the nut pulls the bearing cap down it would hold the broken piece into position. The majority of the force on the bearing is pushing up into the bearing cap. I'm just throwing ideas out there as this head will be on my "spares" shelf, and may only get used if we live in the world of "Mad Max" or "Book of Eli", but I like to have my options.
