24 Valve Cummins Parts — Cylinder Heads, Gaskets & Engine Components
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.
