I would go with a good flush, do it two times and see what happens, Did you check the pump to make sure its working correctly ?

i changed the water pump too. sorry left that out after i changed that thats when my coolant elbows busted.

And make sure you don't have air trapped in the system. Air pockets in the system will cause overheating issues.

How do you get the air out of the system

There is a bleeder valve on or near the thermostat housing. It can be a bit tricky getting all the air out. I've heard filling the system with the nose of the car pointed uphill helps a little, but I haven't tried it so don't know if its true or not. When all else fails it is sometimes worth the money to have a shop equipped with the proper vacuum tool do it because it simply won't cool properly if its not filled properly.
