Here's some info from the final teardown as well as some responses to some of the questions posed. The teardown did not reveal any clear sign of a catasrophic head gasket failure. I inspected the cometics carefully and did not see any burn thru. However, because the cometics are a sandwich 4 layers of material with the inner layers metal, its hard to tell if the exhaust was slipping by the metal layers. I tried some new radiator/block sealer which had the consistency of fine pea soup. One theory is that a head lifted momentarily and alowed some of the filler to wedge between the layers causing the leak. We amy never know. The block bores look great. I'll have my machinist sonic check the bores to be sure.
