Enjoyed it. Happy Thanksgiving to all
If that is a 2006 C6 Z06, you should be aware that GM had manufacturing problems with the heads on that engine in 2006. Apparently the wrong material was used for the valve guides for the titanium valves, which would cause the titanium valves to hang up in the valve guides. Also, on the lower end, the connecting rods are titanium, and galling would occur at the smaller end. BTW, the engine is dry sump. GM has recently discontinued the crate version of that engine. Apparently any deviation in running the engine stock would shorten the life of the engine due to very tight tolerances of the engine and its need for strict adherence to the factory maintenance schedule.
Interesting for sure. This explains a lot. There is no oil tank in the engine compartment. However, the crankcase ventilation system has been seriously altered. Since I read your comment, I've been searching for this information. I did find conversion kits to eliminate the dry sump and convert it to a wet sump. I will keep you posted. Thank you so much for supporting our project.
On the scoring issue in the cylinder walls, do you think it might be a good idea to overhaul the lower end so that the iron cylinder liners could be re-honed or replaced altogether? The crankshaft is forged 4130 steel, and the connecting rods are titanium, but the pistons are cast. Now that the engine is apart, it might be a good opportunity to replace the cast pistons with forged pistons to eliminate a weak link in the lower end.

If the car is a C6 Z06, probably not, (you can check if it is by the VIN) then someone switched the engine (why?) from the stock LS7 to an LS2. If you had taken the time to look after you removed the water pump, plain as day the casting on the block says 6L not 7L. Additionally, as soon as you removed the intake manifold, you could see the cathedral intake ports which never came on an LS7.
I'm guessing this car is just a base model C6 with the LS2 engine.
And one other reason this is not a C6 Z06, they never were offered with an automatic trans.
Now you have all that info for your knowledge base.
