318 water hose routing

[ord27]

I installed the newly rebuild Ac/heater box (thanks Steve).
The previous owner had bypassed everything and ran the hoses in a loop. If I put the hoses back on the "ports" that they fit, I have: the lower hose from the valve, connected to the inner fitting on the heater core....
........the outer heater core fitting going to the thermostat housing
........and the lower (larger) port of the water valve going to the water pump

the "book" seems to show just the opposite

question: how does water flow?
does it exit the thermostat, flow through the heater core, and return to the water pump? or just the opposite?

I drew a flow diagram for my 318 Coronet. Hot source comes from manifold and is the left most hose in the photo. I have AC. Right most goes to water pump
