which heater hose goes where???

[HemiDenny]

I'm putting a 383 big block in a 1970 Duster that was a 6 cyl. Can anyone tell me which outlets on the water pump for the heater hoses I should use for the 5/8" and the 1/2"

This is a photo of a late 440 housing but my stock '69 383 has these connections. Ignore the X location - probably won't be there. If the housing is early enough, there may only be two ports on top and the sender will be located in a smaller hole on the front.
