Hello, I'm swapping a 216 for a 261 (Full pressure - 1962). I have an 848 head on the rebuilt motor properly drilled for steam holes. I was given (loaned) a water pump housing with a bypass around the thermostat. Would anyone have a NAPA number for the water pump I've seen with the dual outlet?

Thanks - Joe
