Ignore the below if there is any question of the condition of the current engine...
If the bottom end is in good shape, there is nothing wrong with a dingle ball hone and hand polished crank with fresh bearings, rings, timing set, gaskets, and bolts (oil pump maybe??). This can easily be assessed by a simple disassembly. IF crank is currently good, no special tools needed. Plastigage is really pretty good with the factory bolts, then assemble with new hardware. NEVER reuse the TTY factory stuff unless there is a super simple re-hack I don't know. Dawn, brake-clean, WD-40, motor oil and assembly lube FTW. Keep it as clean as possible and rock out. I've seen some of your other posts, you can totally do it.
