Industrial Injection's Stage 1 Ported and Polished Cylinder Head With Fire Rings is a great way to get the fire rings seal that allows your engine to handle the higher pressures your combustion chamber can produce when you add higher performance injectors or fuel systems. On top of that, these Cylinder Heads have gone through a porting process that gives unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier. If you are looking to unleash the maximum your Cummins can do this cylinder head is for you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE: Fire Ring Gasket sold separately.
