I think the answer is yes on the radiator port.

On a stock LS6 (e.g. 2005 CTS-V) the hose from the cross over (front only, on the LS6) connects to a three-way tee connector. The other two hoses on that three-way tee connector run between a steam port on the radiator and a port on the surge tank.

Correct, that steam pipe must run back to either an overflow tank or the radiator!
