Terrible job, every bore was tapered or egg shaped, piston to wall clearance was anywhere from .0005 to .0035. Had block inspected by two other shops, had to bore out to .040 to fix it. They ground the margins off every valve but one, ruining brand new valves. If your looking for a shop I would keep looking.
