Does anybody know the direction on the heater core? Inlet and outlet.. Mounting a extra heater on my lbz, so the engine are hot when I come out on the morning.

Heater core refers to the coolant fed cabin heater, with the inlet coming from the EGR cooler.

Or, are you referring to the engine block coolant heater element, down below #1/#3 cylinders?
