You didn't say what type of gauge you are using. If you're relying on the stock gauge to determine temperatures, that's probably your problem. Guessing at temperatures by noting where the needle is is not accurate by any means. I'd guess that your sending unit for the stock gauge is bad and is making the gauge read high. Get a quality mechanical gauge and find out the temperature for certain.

If it's not overheating (and at 260, it should be steaming), then you may not have a problem.

Also, put the thermostat back in. It isn't a restriction, and only sets the lowest temperature at which the coolant will flow. It also serves to slow the coolant down enough to adequately cool in the radiator. Without it, the coolant is circulating too fast to reject all the heat. The thermostat is one of the most misunderstood devices--it can only help unless you put it in backwards or it sticks.

Hope this helps.
