As long as your cooling system can handle the the load and maintain the temp, then you definitely want the 180.

I also run a 160 in my street cars, my big block stroker Duster runs at 178 degrees all day long with an aluminum radiator, flex fan, good shroud, and 160 stat.

I would suggest you also drill a small weep hole in the thermostat, I have had problems with air trap before and the thermostat won't open.

^^^ agreed, a 1/32 hole in the "flat" is plenty & also lets you pretty much completely fill it completely the first time as opposed to waiting for the stat to open. this elims a potential burp of coolant out of the rad neck onto your pristine eng & it takes care of hot metal areas that have no coolant on them when its first fired.

Just leave a heater hose off while filling the radiator and all the air comes right out, I learned something today.

I don't have a heater core or heater hoses in my car but whenever I change fluids I drain my radiator and both sides of the block, then I use an 'Airlift #550000' tool to suck all the air out of the system, then I stick the hose from the kit into my bucket of new fluid and it automatically pulls all the fluid into the cooling system with no air pockets. Best tool I've ever bought.
And I also drill a couple small holes in the base of my thermostat.

at least 180 & on drilling the stat it takes longer to find/chuck up the 1/32" drill bit than it does to drill it. then I chamfer that mini hole with a slightly larger bit by hand, takes 5 seconds.

Running a 160 just delays the onset of heat. Might work as a restrictor once it opens and that might work out for you if it holds the water up enough in the radiator to lose the heat. I found replacing a 160 in a car I had made the oil stay much much cleaner. I put the factory 195 in it and it stayed right on the stat all the time. Even idling for long periods with no shroud.
The real deal is system capacity. Get that right and it will be fine. Engine masters did Dyno testing and a clutch fan without a shroud was the best engine driven setup. So I'd run a 180 or 195 with a big radiator and call it good. Get outside intake air piped in and you'll have a nice rig.
I want my fair share

There is a lot of info on this subject on the WWW. Here is just one link, but it is consistent with most of the others and is easier to read than some others. What it says is that there is double the engine wear at 160* as there is at 180* with no appreciable performance gain. And if it matters, I always drill a couple of small bleed holes in my thermostats. Which, after some bad experiences with other brands is only the Stant Superstats. http://www.carnut.com/ramblin/cool3.html
