As far as dry film lube goes I may use some dry Teflon spray on the rod and main bearings, just like I did when I built my diesel engine.
I expect it to be long gone by first oil change.
I would try coating but this engine pull was a little unexpected and I need a fast turn around, normally I take as long as needed to accumulate parts and funds to do what I want. All the machine work, roller this and that, aluminum heads, conversion to internal balance if I had time it may not be in the budget at this time. If I pull the heads later on I may have them sent off to be coated.
I would really like to have full roller cam bearings but the time constraint does not allow it.
I am thinking I will just use -20'F windshield washer fluid which starts you out at 40% alcohol. If I need more than 40% I may boost it with yellow bottle isoheat fuel deicer. I have alcohol hydrometers so I can mix and remix it as needed. I would mainly use it for hard take offs and not jettison the leftover.
The freeze plugs look innocent enough but they were a pain to get out, a few of them were paper thin. Thought I might have to grind them out.

I just used a wood chisel, hammer and vise grips to rip them out.

They cast that into the block incase you don't know what it is.

They may look shinny in the picture but they are not. There are rust spots and cylinder bore taper.
