Need more heat

[Yankeelights]

Northwestern PA winters are cold and I need more heat. Aside from possibly having critters taking up residence in the heater core box and restricting air flow with a nest, I'm wondering if my hose configuration is keeping the heat from the cab.

Right now, one hose goes from the intake to the heater core; the other hose is connected to the right side of the radiator.

Would I get more heat by moving the hose from the radiator to the water pump port?
