fitting a mkiv radiator w/sc300 overflow on sc400

[poorsupra]

looking to put in a nice koyo 3 row aluminum radiator along with a sc300 coolant overflow bottle on my 93 sc400. my question is what should i do with the smaller stock coolant line that supplies the sc400 expansion tank? should i block it off somehow? does the mkiv /sc300 provide adequate expansion?

Block it off, and run an overflow tank from the Rad cap.
