The bolt that broke on initial reassembly was a used one. I destroyed the old head getting the rounded bolt out, but was already going to use a reconditioned one I had bought on ebay anyway, so no big deal. I did oil the new bolts. We will see if not torquing completely to specs comes back to haunt me. I would say that even with just 90 degrees rotation past 44 ft lbs they are still at 90-100 ft lbs anyway. Should be good enough for all but nitro burning dragsters!
