heater core supply & return?

[65wildstang]

Which one of the two tubes on the back side of the motor is the supply for the core and which one is the return? I was thinking the driver side was the heater core supply and passenger is the return? Just want to make sure before I start cutting hose and plumbing. Thanks

Back of the passenger side head is the feed.

If you have a fitting on the drivers side it is a version of the head cooling mod.
