On the photo from 12/8 showing the firebox tubesheet to crownsheet joint, about what size gap did you guys start with? Also, is it cheating to tack up and then gouge from the same side, finally going back to gouge out and finish weld the spots with tacks?

When fitting the outer firebox to the shell, depending on the type of firebox, tacking and back gouging is common.
