Junkyard 5.9L Magnum + Edelbrock LA heads build

No need to re-bore with new rings. Just hone. I get what you are doing 100%. My point was not to discourage you, but to dispell the idea that new rings would fix bore issues. It was all about that word 'longevity'....

I hear you, all valid concerns. Well in that case I'd be concerned about getting the correct crosshatch pattern, I don't want to ruin my cylinders if they're already in say, 90% good shape? And stripping the block and hauling to my machinist sounds like a pain just to get a hone. HOWEVER... my machinist (actually it's a team of 2) is a badass and can probably take one glance at my block and tell me how it looks and if it needs anything. These guys are used to building 1500-hp BBC drag engines and crazy giant-turbo LS monsters so I trust them for a moderate street SBM build.
