Help with this 8BA

[Vonn Ditch]

So I bought a basketcase 49-53 Flathead that had been stored unassembled for years. We pressure washed and cleaned it up and checked it with magnaflux. No cracks presented themselves. It's a standard bore with only slight ridge at the top of the cylinder. Here's the problem, the engine was taken apart and nothing was marked, rod end caps, mains, all unmarked and loose in a box. How should I proceed?
Thanks
