225 running a bit warm!!!

If it is a flow issue then removing the thermostat may help but I wouldn't recommend it for more than just a test period. Remember that thermostats are there to keep your car from running too cold, not too hot.

I would try the following:
Back-flush and put some kind of cleaner in the system.

and

Check your spark-plugs. if you are running rich or lean you will overheat.
Run a can carb medic through the carb.

and

Make sure your EGR valve is not stuck shut.
Not completely true. In some systems, it will overheat without a thermostat in place. If the coolant flows too freely, there is poor heat transfer to the radiator/air. Rich running won't cause an overheat problem.
