Did you bleed the air out of cooling system after the first flush? Sounds like you have an air lock in the cooling system. To bleed mine, I raise the front end up about 6" to get the radiator as high as possible. Run it until the fan comes on. The Tstat will open. After the fan kicks on, shut it down and carefully remove the radiator cap. Start it back up and run it. You should see air move through the system and out the top of the radiator. The air flows through the coolant, to the highest point, so that's why I jack up the front end so high. May need to do it several times, but it eventually will work its way out. I installed a coolant recovery jug on mine. This really worked out to be a good move. No more puking or overheats.
