This is the liner mating surface for #4:
52334

Should I just save myself the trouble and look for another block?

Once this happens the over all integrity of the block is usually compromised in other ways as well.

What's the next best option? Find a "new" upper block?

Yes that is the next step.

Not that I'm at all recommending this but... I had pitting like that in one cylinder in my block (but not quite as bad as your picture) and a local machine shop fixed it using some sort of epoxy. They filled the pits with the epoxy an used an old liner to press the surface flat before it hardened.

5 years and 37K miles later and so far so good.

Though I probably would have been better off getting a new block. Shortly after getting everything back together and running I discovered a pinhole coolant leak in the block that I had to patch in an ugly way. http://dmctalk.org/showthread.php?8061-Block-coolant-leak
