Like JSeery, I can't understand how anyone who calls them self a machinist would assume what was wrong without measuring the pistons and the bore again. As stated above, you have to know the clearance recommended for the pistons to bore and hone the block which apparently has been done. Since we are dealing with a fresh bore, there won't be any taper so simply measuring the bore and a piston should clear up what the size actually is. Perhaps the boring machine was set wrong or set to a metric value or some freak thing like that whatever it is it shouldn't take more then 5 minutes to zero in on what you have and what you need.
I'm sorry that you are having this "experience". Don't let it sour you on the engine, it should however sour you on the shop where the work is being done.
Good luck and I hope you have a good resolution.
