Please post how you finally correct the problem. I've got a spare engine with the same situation. I had thought about drilling out the original fittings,tapping the head and installing brass hose barbs.
   The forward (smaller) nipple is for the TB heater which I plan on deleting this summer while the aft fitting is for the heater core, have to keep that one.
