Reply to "Goose 8MA642 Refurb and Repaint"

Am prepping for engine stand run of rebuilt motor and plan to use rebuilt radiator to test it. The picture shows a port at the top circled in red that was connected to the overflow tank in the engine bay since I've had the car

The bottom red circled port has been blocked off since I've had the car.

What is the correct connections for the coolant going into the radiator other than the main coolant input coming in from the thermostat housing? Should I be running the hose from the overflow tank to the top port (way the car has been for years) on the radiator, or the bottom port (blocked off for years) on the radiator?

Thanx
Mark
