Default Doing an LT5 Full Rebuild, Should I replace the Cylinder Liners?

Opinions needed on this one.

I own a 1990 and decided to buy a spare motor when one came up for sale on here for a good price.

It's a 1991, the motor out of Dave Davis's wrecked Black car.

The last time it ran was when he had his accident (2008) and it sat garaged with all the original oil leaks and grime since.

I got it last week and tore the entire thing down. Since this is the first time I've had one of these apart, I was looking for opinions (hopefully backed with some knowledge...) on a few things. I've attached pictures of the liners. I don't think they look bad for having over 100,000 miles on them. Once has a noticeable gouge, but I'm unsure of whether I should replaced the gouged one, re-ring, and go, or replace them all while the motors apart. If I replace one or two, I'll try to find some low mileage liners. If I replace them all, I'd like to go with OEM liners. I do have a complete set of liners/pistons/rings that I bought from Jerry's less than a year ago, but should I just throw liners in, re-ring, and use reuse the pistons if they look alright?

Also, on the main bearings, I know Jerry's sells a stock kit and .0005 oversize kit. What journal/bore size would dictate the oversize kit.

I'm a manufacturing engineer who was a machinist before I finished my degree, so I tend to be picky.

Thanks for the help.
