thermostat removal

I have a 416 stroker 340. I have a griffin radiator with custom built griffin shroud and twin electric fans. Edelbrock heads and doug headers. They other day I drove a bit. It was about 93 degrees. My autometer temp guage crept up to 210 and I was getting a little nervous. I have a 160 degree thermostat. I also installed the higher flow mopar water pump. My question is, would I get better cooling if I just remove the thermostat all together? I do not drive the car in the winter? Also, I found my autometer gas gauge to be way off. My autometer voltmeter was readin 10-11 volts but when I put a fluke meter to the battery, it showed the alternator charging at 14.5 volts, so I am assuming that the volt meter by autometer is not accurate as well. which makes me wonder about the autometer temp gauge? How can I test for a more accurate reading and are there gauges that are better than autometer? Thanks.....
