970 Cylinder Machining?

[uknowstu]

Hi! I have a 2010 Panamera 4.8l tt that I bought because it had a water damaged engine. Tear down is complete, and I have the parts that need machining at Patterson Elite (Patterson Elite | Custom drag racing engines and components). Although I just dropped the parts off today, by this afternoon Todd Patterson had a challenge for me. The block is one solid piece of aluminum (so it seems), therefore the cylinder walls are aluminum and do not appear to be sleeved currently.
The water damage bent a rod and the result was a scored cylinder, so the challenge is...how do we machine this cylinder? It seems if we follow the standard boring process, when the new pistons and rings go in, the rings will severely score the newly machined cylinder.
Does anyone have any idea how they built these cylinders at the factory and if this engine can even be machined?
Thanks!
