It probably would not take much, that common wall bolt is at a really high vacuum area at the bowl.

Yeah. I think that might have been a candidate if it was only in one runner. I made that tiny breakthrough on the first headbolt bulge I did, which was #3 or #5 depending on which way up I had the head when I started. Whatever I am dealing with is in most holes on both heads. No other breakthroughs happened.
