Absolutely true. Ideally, you'd hone the cylinders (with a torque plate) after installing the sleeve. But then, ideally, this would have been caught--and sleeved or otherwise repaired--long ago. You're probably going to end up with some extra piston-to-wall clearance, but that doesn't mean the party has to end. Your machinist will have to measure--and be careful. Why? IF (big IF) you have seven good cylinders, there's no reason to carve 'em out and shove in sleeves. Sleeve the one bad hole. The question here is whether or not the other seven are good. Even if you sleeve all eight, you could still have the machinist bore 'em to fit the pistons. That assumes the machinist assembled the engine. If someone else did the assembly, they may have caused the gouge--and the machinist may do fine work.
