24 Valve Cummins Parts

Head gasket failure on the 24V is most common in high-boost applications and engines that have seen overheating events. O-ringed heads with quality studs and MLS gaskets are the proven solution for performance and high-mileage rebuilds.

No. The 12V and 24V Cummins use different cylinder heads due to the change in valve count and combustion chamber design. Confirm your engine generation before ordering.

The 24 Valve Cummins introduced VP44 injection and a redesigned head for more power from the 5.9L platform. Head gasket integrity and valve train durability are the primary concerns for high-mileage and performance-built 24V engines. Parts here are chosen for trucks that work hard and need to stay that way.

O-ringed heads are a standard upgrade on performance 24V builds, providing significantly better combustion sealing under the boost and cylinder pressure these engines see in modified applications.

Heavy duty valve springs are a core upgrade for any 24V build running more aggressive cam timing or boost levels beyond the factory design envelope.

All cylinder heads here start with new castings — not remanufactured cores — for consistent quality and no hidden wear.
