eninge machine work

i was very disappointing at the work they did.i took my block amd they messed up on one of my cylinders when boring it .0020" over and started at .0050" instead for about .0050" deep. so now my # 2 cylinder has a stepped ridge where the deck and bore meet. i realized after they did the work that they dont use torque plates, witch is very important. my fault i guess for not asking. i just assumed they knew what they were doing. as far as them cleaning it, it was full of metal shavings and the water jackets had rust chunks falling out of them. dont go there for machine work. if you do and your not driving a chevy they dont seem to care about your engine.
