Industrial Injection Stage 1 Ported and Polished Cylinder Head With Fire Ring Groove 89-98 Ram 5.9L Cummins

Have you gone above and beyond for the power output of your 12 Valve Cummins? More power equal more compression and pressure in your engine but can your stock Cylinder Head take it? Extraordinary power requires extraordinary measures and upgrading to a fire ring gasket is the best way to avoid a blown gasket. Radius-cut fire ring grooves create a stronger, more reliable combustion seal, allowing a 12-Valve Cummins engine to handle higher boost and cylinder pressure without head gasket failure. If you are planning on pushing your Cummins power to the limit, ensure your engine can withstand the extra stress that higher-performing injectors and fuel systems can impose with a cylinder head designed to handle it. Get an affordable and reliable upgraded head with Industrial Injection's Stage 1 Cylinder Head.
