my /6 runs hot

If it is pegging your temp gage it should be loosing coolant out the over flow pressure hose at the cap that should be going to some kind of a catch bottle, I use a N.O.S plastic energy drink bottle, Is your gage showing a true reading ? If the engine is that hot after 2 I would be concerned that the new pump is not working and not moving coolant... Can you see water movement with the cap off ? if not something has obstructed flow or your pump is not working.
Do a coolant flush and fallow instructions, Your timing could be set to high and or the carb is running lean, Did this just start all the sudden ?
First thing I would do is start it up when the engine is cold and when you see your temp gage read half way our straight up is should be HOT!! open the hood and feel the top radiator hose and squeeze it and see if there is high pressure and VERY hot , If not your gage is giving you a false reading8-)
