I am having a hard time following just what was done to this head and this barrel. This head was done in a bridgeport with 20 thou off? And then you have taken sandpaper to it? These barrels were resurfaced? How do you know where you are at now?
Has a stud been put in wrong way round and pulled some metal up round it?
Do a search here on John Healy and head straightening. It is much better than resurfacing. I can understand why you feel attacked. I have found that when I do something that I think is best, and it turns out to be wrong, I feel terrible and defensive.
