hotter than I like to see but check accuracy of your guage and give us some more details about the install---underdrive pulleys?? what water pump???fan?? radiator and shrouding??? change your type of fuel/gas???? different oil???

Jerry makes a point especially when it comes to pulleys. The pump pulley should be smaller than the crank pulley. That will put an overdrive on the water pump. That will drive the pump alittle faster at low speed, which will push more coolant. Also is the fan shrouded? if not it should be.
