Keeping car cool
If you are dead seat on a stock rad you could pick an LT1 rad up, they have a thicker core than the LS1 rads
Do you have an air dam on the car still? if not make sure you get one on there. These cars are bottom feeders.

FWIW 220* isn't too hot. My stock C5 sees 220-225 everyday. Second fan doesn't even kick on till 225. I'm not suggesting you race with it at those temps, but they aren't hurting anything sitting in traffic.
Goof luck.
Ensure fans are mounted correctly, flowing correctly, have adequate power supply, and airflow through the rad etc and also out of the engine compartment is efficient.
