In terms of basic function it really doesn't matter which hose you select as the inlet to the heater core and which the outlet - the coolant flow in the engine determines which way the water will flow and the heater core will get just as hot in either direction. The only difference is whether your heater control valve (Ranco or otherwise) will be regulating the flow going to or coming from the core but the function still remains. That said, why not hook it up correctly.
