I wouldn't be so quick to make a blanket statement about the 140 heater flow. You are correct that the pressure side (feed) is from the elbow at the back of the head--and the return is to the pipe going to the back of the WP. BUT -- during its production run I do know they changed things a bit regarding the hoses. Heater hoses for the earliest 140s (I don't know --maybe up to '69 or'70?) are different than the later ones. I think one set used the valve to block coolant from entering the heater core and the other path blocked its return. -- Dave
