Magnum 5.9L rebuild data

There are rebuild kits available for Magnums. I'd check with a local machine shop, they might get one at a fairly decent price. What are the issues with the engine?
Issues I have it’s the cylinders (1,8) looks like it have damages. And I’ll need next size pistons and rings? (What size?). The crankshaft should be polished- don’t know whats the next size of bearings? Cam, main? Also they’ve asked about sizes, diameters of all the rest I could find. Is there any manual for such engine rebuild?
And on top my pkan is to balance my crankshaft, to make it balanced with front harmonic balancer and with my torque converter.
