With a clear head, I would have seen that the bolt snapped in the head and not the block. I assumed it snapped in the block and would require a drill and easy-out. In hindsight I could have found a wooden dowel or tree branch the correct diameter and length. With this I could have tapped it with a hammer to imbed it onto the broken stud and unscrewed it. It was not tight in the block, it easily unscrewed and it stuck up at least a 1/2" and the break was not flush and smooth but very jagged. I could have saved a head gasket and some time. I would have replaced just this bolt. But in hindsight this bolt didn't feel like the other 13 during torqueing and I should have removed it to inspect it before it broke. After it broke I was trying to think of someone I new who was mechanically inclined to call and just think through with my thoughts and I couldn't think of anyone I wouldn't be imposing on. So I went with my gut to rip it all apart and start over. My advice to you is be more patient than me and let the helpful folks on this site help you think it through.
