I used water wetter in the 67 for a while. It does help, but only 5 - 7 degrees. However, this was with 50% anti-freeze. The higher the anti-freeze mixture, the lesser the effect of water wetter.
What's the climate like where you live? High temps? Humidity?
Just cruising around, taking it real easy, 220 is okay IMO. However, I would NOT get into boost at those coolant temps.
Short term, maybe you could try water wetter and 100% distilled water. This mixture has the best heat transfer properties. Water is better at transfering heat than anti-freeze. You could run that mixture to both see the new operating temp and allow the engine to break in a little more.
