It sounds like you have a new crank, but I had a machinist tell me BB mopar cranks have a rep for being out of square on the throws so the piston deck height can vary from hole to hole when you check them. He index grinds them to cure that.
I had a block decked once and had to have it redone by another shop as out of square was the best work the first shop was capable of. Some people make a living getting things close enough and hope you never check their work. Live and learn.
Sounds terrible, the machinist i use here in Sweden is a good well known one, he know what he doing and because of that he have alot of work, in here they not be long lived if they makes mistake like that. The crank is new and checked up. The engine running great so its all good, i was just courious about if it was common with varyation in deck height.
