The machine shop messed up. Likely misadjusting the machine during boring, causing damage to the top of a cylinder bore. The engine block was bored .030 over and decked at the shop. Are the damages something that can be fixed or is the engine block scrap? My concern is that it may not be possible to install the pistons without damaging the piston rings, especially if the piston needs to be removed later. Unfortunately, I noticed this when unloading the engine block from my car after picking it up, so I couldn't confront the staff directly on site.
