Currently all flush is out the petcock.. Monday, I will be removing the upper hoses and flush directly down the heads. see what comes out. Then flush flush flush, and repeat with the Thermocure. .. run the engine... let it cool and flush more.

Sounds good. You may want to remove the upper hoses and thermostats then rotate the hoses on the heads so you can get them close to vertical. Remove the lower hoses. You could run a hose from your hot water heater drain line to the up ended radiator hoses for a flush.

I found on my 59A the even with hot tanking, there was sand and junk just inside of the water pump connection so perhaps pull the pumps too.

I have also found (suggested here in FordBarn) No Rosion and another alternative for crap removal .. and then after a complete cleaning.. addition of an inhibitor which I am researching, .. I am also in Maine, but store in warm garage.. so considering water only or 50/50 for the coolant.

There are no freeze plugs on the 59AB, too bad they could have saved a bunch on blocks. Pic below is for a 39-40 block.

Don't run with just water. Antifreeze has rust inhibitors and also gives you a higher boiling point than H2O
