If it was mine.....I’d do a complete clean out of the cooling system. Pull the radiator and test the flow....pull the water pumps and clean out as much as I could. Leave the thermostats out for now till I got the overheating problem resolved. When this was done, I’d check timing, carb and make sure I had an accurate temperature gauge when I test run it this first time out. You really don’t want it to boil over anymore.......Mark
