Well the lack of a thermostat is a good reason for the heat to not work, it will also cause the engine to be too cool in the winter and overheat in the summer( put it back ). The coolant is blowing back through the overflow because your radiator cap is bad, or there is a leak in the head gasket and exhaust or compression pressure is enterng the coolant system. I would check the cap first.
