I actually had a pretty good idea of the condition of the cylinder walls before I tore off the heads. I used the borescope through the spark plug holes first, then tore off the oil pan for inspection. I could already see the crosshatching through the borescope before disassembly. If anything had looked 'wrong' or overly worn, I wouldn't have torn it down, and simply returned it for a better motor.
Here'* the #2, 4, and 6 cylinder bores:
