Those cylinders look great. What brand of camera/borescope?

Four pages is a lot to review. Might help to summarize where you're at in the process. Cylinders look like they're ready for fuel, air, and spark.

I would think the motor oil you're using squirted down the spark plugs holes would be good and take the valve cover off add soak the cam and valve train. Then turn it slowly clockwise from the the front and notice any hang ups or anything but smoothe rotation over and over. Leave the plugs out and use the starter but don't crank too long, short burst as to not burn the starter up. You will need a battery charger and don't rush the process, feel the starter and if it gets too hot to touch call it a day.

The coolant should be all the way up to the top of the radiator fill hole. Let it run until you see the coolant flowing. I would add some water to your coolant, it looks to be straight antifreeze. That's not bad but 50/50 is what most people do.

The only change I would make to the excellent info above would be to use Marvel Mystery Oil. It contains mineral oil and a solvent that dissolves anything sticky or gummy.
