Don't go with a 160, it will open too early and the engine will stay in warm up mode.

Agreed, I think 160 is too cold. 180 is pretty much perfect. From my experience, you can get considerably worse mileage with the 160 as well.

160 for a blower isn't uncommon in carbureted setups, since it can keep the heads a tad cooler and hold of detonation...which matters a lot if you're running crappy old roots blowers cuz they make huge amounts of heat. But carburetors don't have open/closed loop operation like EFI does. So yeah, don't go lower than 180 or you'll be running rich.
