It can be difficult to burp the heater core and the bypass hose. The bypass is what controls the thermostat it is a goofy setup. What I did was put a Preston flushing tee in the upper heater core hose on the engine. Remove the radiator cap and hold the tee above the radiator and pour coolant in the fitting until coolant runs out the radiator. Start the engine and top off the radiator if necessary. When the heater is working the bypass is primed. There is a two piece thermostat housing that goes on the intake manifold if your lucky enough to find one. Then the bypass goes from the upper thermostat housing down to the water pump then just plug the bypass fitting on the intake manifold.

Thanks for the heads up. I clamped off the heater core hoses before I disconnected the top end housing. Then when I put everything back I poured the water down the upper radiator hose through the engine block until it came out of the radiator. Then put the hose back on the radiator and topped it off from the cap. Turn the heater on and started her up and no problem since. Now it’s on to the duraspark conversion!
