Most con rods were numbered but not all. They can still be used but some form of ID check on the cap bores needs to be done. On the mains, there is a 50/50 chance you can get them back in proper order since the rear main cap is unique. All of these can be align honed at a good machine shop to eliminate worries. Check the caps for indented center punch marks too. I usually mark the with 1 dot for the front main and 2 dots for the middle. I would have the engine bored with new pistons if the wear is beyond service limits.

Consider a pressure test of the block. You can have cracks that are not visible by magnaflux. It's the only way to be sure there will be no leaks.
