You are looking at something else then. Thermostat housings are not part of the block!What you have is 1/2 inch pipe thread try getting an extractor on the broken piece, use a little heat from a propane torch, then back it out with the extractor. If you follow the upper radiator hose to the engine, you will find the thermostat and it's housing. You might be looking at the waterpump, the heater hose outlet is as you are describing! If wors comes to worse replace the entire pump, it comes with the outlet on it!
