Ouch - these much better pics point towards a minimum of polishing or turning the crank .010 and new rod/main bearings, including R&R on the cam bearings.. What we are not seeing is what is the cylinder bore wear given whatever happened in this engine that scored the bearings. (Dirty or wrong oil, what was found in the oil pan?)
If this was my engine, I would have it at a good machine shop, turn the crank, hone or bore the cylinders, new pistons/rings if necessary, and as long as it is disassembled, get it balanced. Then you have piece of mind and a reliable motor going forward. Yeah - this costs much more $$ than just bearings, but eliminates spinning a rod or main bearing, or god forbid throwing a rod. That was exactly happened to my Bro when we cut corners on his rebuild
