Engine Operating Temperature

[chtr65]

Just fired up my 65 1/2 ton after having the original radiator recored, and I'm not sure what the operating temperature should be. It is a stock 283 with a 650 Holley. The temperature went up to 194 degrees in about 6 or 7 minutes of idle with the heater on. I just installed new transmission cooler lines along with the new radiator core. Thought maybe someone could shine some light on this. I thought the temp should be around 180. I did turn the heater off and the temp seemed to rise another 8 degrees. Would the temperature drop if I took it out on the road? Thanks for any help.
