"all the washers were replaced with aircraft-quality machined flat & parallel washers."

Are the washers HARDENED??? They can not be soft.

Just be sure that the head bolt boss at the top of the ehad is parallel to the mating suface of the head. Most auto machine shops do a sloppy job of resurfacing heads and in the process the resurfaced area may be at an angle to the original sufaces of the head stud bosses at the top of the head. My gues is that + or - .005 inch variation from one side-to-side of the boss would be ok. Maybe check an NOS or other know good head to see.
