Cracked head, water in the oil

[Poor Richard]

The steps I suggest:

Dump existing oil milkshake from engine

Fill with fresh oil, crank the engine over for a few seconds but do not start it.

Repeat that process until the obvious water contamination has been removed.

When I say "obvious" I mean "the oil looks milky". You want to eliminate that first before firing the engine up.

Once the oil comes out clear-ish looking, fill with oil and run it up to operating temp.

Shut the engine off and let it sit for at least 5min.

Check oil level and visual quality of oil.

Edit: if you're worried about damage to the engine, consider an oil analysis from a lab such as Blackstone

I used to go to M & M in Meredith for used parts and once, an engine. I think they closed awhile ago. What happened to their inventor? Anybody else in that business?

So I was able to get all the milky oil out with my hand pump. I put in a quart of automatic tranny fluid before I started pumping to try and thin it out. Seemed to help. I'll try one more qt of tranny fluid after I reassemble the engine to try to get some more contaminated oil out.
I like your recommendation of cranking with fresh oil but not starting then doing another oil change. I hope to have it reassembled by beginning of next week.

Thanks for the tips!
