Additionally, I observed the "finish" on them to try and determine if they might be cast iron, chrome, or moly. They appeared shiny as if they may be chrome. However, I suspect any type of metal ring would be somewhat shiny after thousands of miles of wear. So I'm not very confident my conclusion is accurate.

I know some of you folks have built plenty of engines in the past. I intend to wash the cylinder block as previously suggested. Having done this in the past with other engine blocks, I find myself scrambling to dry and oil the block before the blazing-fast-rust sets in. What have you all done? Any special tips, other than scramble fast to dry with compressed air and then oil the steel?

Drying out the cylinders with say cheap Harbor Freight Terry Cloth and then wipe down the cylinders with trans fluid should prevent the flash rust. Any other metal areas spray down with WD40.

Yes, I'm working on the aluminum LNF block. The liners are one area of concern. Wiping the inside of the liners is easy. However, there is a small slit at the deck surface between two adjacent liners where water can ingress and get on the liners' outer diameter. For this, I suppose I'll just do my best w/compressed air and WD40 to attempt removing as much water as possible. And there are a few steel pieces pressed into the block (e.g., a steel tube pressed into the oil filter housing for connection to the oil cooler; the cylinder head roll pin guides; the bedplate roll pin guides).

Great idea. In fact, "assembly lube" might be better choice since it is stickier. However, my question pertains to the flash rust that occurs instantly on the steel after dousing w/water during wash-down. I want to minimize this as much as possible.

Rust on the pin guides is not a big concern. If they get a little rusty, hit them with some sand paper right before assembly. Also clean out the matching pin guide holes. (Dremel tool)
The liners and pick up tube. After cleaning, coat with a lube of your choice.
Yeah. Back in the day I built a few iron block, iron head V8's. The parts would come back from the machine shop cleaned but I would reclean the block and heads good, then wear out the compressor trying to blow them dry.
Gotta have a clean surface when spraying Chevy Orange or Oldsmobile Gold engine paint. Ahh,,,, the old days.
