Being in Pensilvania, you could go for a 180, but I would avoid the 160 due to cold temps in winter.
Now mind you a 160* stat doesn't men the motor will run at 160*. It just means the coolant is allowed to flow through the motor once that temp is reached.
LS1/LS6 were designed for efficiency at above 195* and like to run at these temps.

I ran the 160 in my previous car, it seemed to be ok. Scanning while driving it, the coolant temps stayed in the 180 range, 182-184 IIRC. The fan settings had been tweaked as well of course.
On my current ride, I chose to leave in the stocker after not finding any hard evidence of the lower units being a benefit.

I run 180, there are some advantages to a 160 like reduced spark knock etc. if the engine actually runs cooler. Most OEM radiators are marginal at cooling a motor.
If your motor runs 160, it can cause an increase in wear on the cylinder walls.

160 here and my temps stay at 172. I may have to change that though as predator stated optimum temp is at 195. I didnt realize that. I thought cooler was better. Less chance of the motor detonating but you learn something new everyday.

I am running a 160, but have my fans set to try and keep my temps between 175 and 180. I made the most power on the dyno at 180, but it started falling off and getting more knock by 185.
