You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

if you dont see a radiator cap then the cap for your resevoir tank also serves as your radiator cap, thats where you would put your radiator cleaner and dex-cool in at. it is pressurized just like a normally radiator is with a normal radiator cap on it so dont open it when its hot! the resevoir cap should also have dex-cool stamped on it

You have combustion gases getting into the cooling system, that much is sure, if u didn't have the headed for poss warp-age then a new head gasket will leak, these heads warp really bad, we always have them trued up or we won't guarantee the job.
