Should you replace both radiators.

I used the airlift initially and put about 5 gallons of distilled water in. I rev at 2000 for 15 minutes until the fans come on. Even though the radiator return should be cooler, I think it should at least be warm.

I was going to take it off the jack stands and go up/down some hills to try and burp it that way. Whenever it gets to 200F, it starts to overflow through the radiator cap and I wait 2 hours before trying again.
