I don't recall ever seeing this explicitly addressed on the list before, but have seen some pics...

What are the sizes for the heater hose/water hose outlets on the rear iron. One big one next to the Oil Pressure sensor.. and a little one on the top, opposite of the big one.

What are people doing with these to plug them off? or where are they routing hoses from them to?

The larger one near the oil pressure sensor is designed for standard automotive 5/8" heater hose.
The smaller one on top of the engine makes a great air vent, connect it to a shrader valve. I got a shrader valve with a 1/8" npt on the other end at napa auto parts, it's called a "tank valve". This valve is located near the coolant pressure cap, so I can release air from the top of the engine while topping off the coolant. In the car it uses 3/8" hose and makes a little coolant loop that ends at the back of the water pump, and is used to increase the idle speed when the engine is still warming up.
