Does anyone know what heater core line is the outlet to the heater core on the engine side and which is the return? I've tried looking for a diagram but have had no luck. Working on plumbing my heater on my hemi swap using a classic auto air system. Thank you?

For what it's worth, here's how my 5.7L is.

My driver's side line goes to my heater control valve [Vintage Air]
My passenger's side line goes to the heater core directly
