Head fire rings 2012 Cummins isx cm 2250 with 380k on engine. Started getting compression in radiator so I pulled the exaust manifold and looks like its coming from number 6 hole. Haven't lifted the head yet so I'm hoping just a gasket and not a crack. My question is.... I know of guys getting fire rings cut in the heads and they are saying that it helps the Cummins head gasket from blowing out.... has anyone had experience with fire rings and what are your thoughts? Thanks | |||
