what degree thermostat?

Any recomendatins on what degree thermostat I should use? 67 Dodge Dart re built 273, bored .020, 4 barrel Isky cam, 2 barrel, automatic, stock, stock, stock. Mostly used for summer/spring/fall cruises, some parade duty. Any brand suggestions? Just the cheapy Gates brand or is there something better. Seems like I used to run a 160 degree thermostat.
Thanks
