Finally... got that head off. Head gasket is blown. Now to figure out why. There are a couple of dents or scratches on the block right where the fire ring sits. I don't know if that would cause it to blow out but I would bet it's not ideal. I haven't pulled the gasket off the head yet. The caliper reading is the largest I could measure of the #3 cylinder. Heads are #3769974.
