You need to take a laser temperature gun and check the top core of the radiator and see what temperature your getting. Maybe somewhere between 150 to 200 degrees? After that, check the bottom core and see what you have. Maybe 110 to 140 degrees? If that is the case, you are simply overfilling the radiator and it is barfing out the excess.
You must remember that this is a thermo-syphon (BARF) cooling system with a water pump hung on the engine to assist.
My 1926 Model T thermo-barf system without a water pump, cools oh so well. It is even a three tube crap for a radiator from the era. Everyone tells me that it can't possibly work, but it cools as good as the day it was born.
