On a reverse rotation water pump which outlet on the pump goes to the heater core and which one takes the small water bypass hose from the thermostat housing?

Same ones as before. Top one to the bypass and lower one to the heater.

Everything works the same if I'm not mistaken. The only difference is that the impeller is designed to pump coolant through the same passages while being turned counter-clockwise due to the serpentine belt routing.
Otherwise everything flows the same way as always. It's not like one of the other engines such as GM and perhaps newer Fords too, where the coolant actually flows through the block differently.

Both nipples are inlets to the water pump. They are interchangeable. The only outlets for the water pump are the 2 ports going into the block.
