Cummins ISX SOHC Cylinder Head — Stage 1 Through Stage 6

Available For: Cummins ISX (SOHC / Single Overhead Cam) Engines

Match the right cylinder head to your application with six available stages, from an economical fleet replacement up to a fire-ringed performance build. Options step up through Grey Iron and Compact Graphite Iron (CGI) castings, Inconel exhaust and intake valves, and stainless steel fire ring machining for a better head gasket seal. Use the chart below to compare stages and SKUs.

Warranty: All cylinder heads come with a 1-year warranty.
Stage SKU Casting Material Valves Best For
Stage 1 055843 Grey Iron Standard Exhaust/Intake Great economical option for a fleet.
Stage 2 055599 Grey Iron Inconel Exhaust Valves Upgraded exhaust valves on the exhaust side, to Inconel metal, to prevent dropping a valve.
Stage 3 056043 Compact Graphite Iron (CGI) Casting Exhaust Inconel Valves CGI casting is more resistant to heat and preventing cracking, with upgraded valves to Inconel metal. Inconel is more resistant to heat, to prevent dropping a valve.
Stage 4 Best Value 054886 Compact Graphite Iron (CGI) Casting Intake & Exhaust Inconel Valves CGI casting is more resistant to heat and preventing cracking, along with Inconel valves — perfect for those looking for a strong head for a performance work truck.
Stage 5 Fire-Ringed 054842 Compact Graphite Iron (CGI) Casting Exhaust Inconel Valves with Stainless Steel Fire Ring Same as Stage 4, but with a fire ring on each cylinder to help better compress the head gasket for a better seal — best for high horsepower engines.
Stage 6 Fire-Ringed 054389 Compact Graphite Iron (CGI) Casting Intake & Exhaust Inconel Valves with Stainless Steel Fire Ring The strongest cylinder head we offer for working trucks — CGI, Inconel valves, and a fire ring to reduce the chance of cracking cylinder heads.
