My friends 6.4 blows the degas cap every time he races with the 485 TUNE. He has a egr delete kit with new Rbp studs and gaskets. Installed by the ford dealer
There are no ARP gaskets, and I don't know what RBP (other than the wheel and grill company) is. Since you posted in RCD, I will assume you mean that...RCD sold the Black Onyx gaskets for a while, which were notorious for having issues (they have since switched to an OEM style I believe)...doesn't change the fact that if the dealer didn't check the heads beyond what Ford tells them to do, there is no guarantee that they are flat or without cracks, which will lead to HG issues later on...
