If your coolant is at 180 degrees while running, I don't think that Skip's pumps will help your problem. Does your car have a 1936 engine? Is the distributor and coil the original type? A couple of photos of the engine compartment showing the engine and distributor would help. The gushing can be caused by many things and the trouble shooting process should be tailored to your configuration. The fan only comes into play when you are traveling at low speeds or idling the engine.

Did you buy the correct 1939-1947 Ford thermostats? The 1949 and later thermostats will travel up the hoses and turn sideways, causing problems. A leaking head gasket can cause the coolant to foam and then burp. A good check is to drain enough coolant to allow the upper hoses to be removed from the heads. replace enough coolant to fill the heads to where you can observe the coolant. Remove the generator and water pump belt , then start the engine. Look for bubbles in the coolant while the engine is running. Bubbles would indicate a leaking head gasket. If you have the correct thermostats and no bubbles, fill the cooling system with the coolant and drive the car until the temperature is 160. Shut off the engine and remove the radiator cap and look at the coolant. If it has turned to foam, you probably would benefit from having your water pumps rebuilt by Skip Haney. Again a couple of phots would help us see if there are other concerns.

I use distilled plain water,with water pump lube, to keep the rust down distilled water does not have any chemicals antifreeze if overheats can be a mess.

gfstew I would suggest you hesitate before you go thru a lot of work or expense, because from what I have read in your posts I don't necessarily see a problem here, other than perhaps an over-filled radiator. You have 180 degree thermostats and the car runs at 180 degrees. When you turned-off your electric fan it was up to 190 degrees when you parked. I would think that is normal for driving at slow speeds. Then with engine stopped it went up over 200 degrees. That too seems normal. With circulation stopped, the coolant will get hot for a period of time as it absorbs heat from the engine block. It then pushed out some water. That would be expected if the radiator was over-filled. The top part of your radiator above the coils is your expansion tank. The radiator should be filled only up to a couple inches below the top, leaving room for expansion of the coolant when it is hot.

One way to check the cooling efficiency of the radiator is to measure the temperatures at the top and bottom of it with an infrared thermometer. With a properly functioning radiator the temperature at the bottom will be 15 degrees F cooler than the temperature at the top.
