6.0L Puking Coolant with ARP studs

[RitsonRanch06]

Ok so heres the deal.. nov 08 heinzelman ford installed a long block into my 06 under warranty. at the same time they rec to do the head studs.... since then i have been running the sct street tune with the egr unplugged.....

ok so halloween night we did a hay ride for the kids and during the stop and go trick or treating my truck started to get hot (212-225) and would not cool down.... turned heat on then the fan engauged then started to puke..... got it back to the house let it cool down, added coolant to the min mark and its been puking since.... o by the way it does have the updated cap on it....

please tell me what u guys think

thank u
