Cummins Engine Cylinder Heads
Cummins engine cylinder heads house key combustion components including valves, injectors, and intake and exhaust passages that regulate airflow through the engine. These components are critical for maintaining compression, combustion efficiency, and overall engine performance. At Advanced Truck Parts, we supply Cummins cylinder heads designed for dependable operation in heavy-duty diesel engines.

Cummins Engine Cylinder Heads
The cylinder head forms the upper section of the engine’s combustion chamber and works with the engine block, pistons, and valvetrain to manage air intake, fuel combustion, and exhaust flow. Proper cylinder head performance is essential for maintaining engine power and efficiency.
Cummins cylinder heads support several key engine functions:
- Air intake and exhaust flow management
- Fuel injector mounting and sealing
- Combustion chamber compression sealing
- Valve operation and timing
- Cooling system circulation through internal passages
Because cylinder heads operate under high pressure and extreme heat, proper casting strength and machining tolerances are essential for long-term durability.
Common Cummins Engine Applications
Cummins cylinder heads are widely used across both heavy-duty and medium-duty diesel engines.
- Cummins ISX CM870, CM871, CM2250, and CM2350 engines
- Cummins X15 Performance and Efficiency Series
- Cummins ISB 6.7L engines
- Cummins ISC and ISL diesel engines
- Kenworth, Peterbilt, Freightliner, and International trucks
Different engine generations may use specific cylinder head castings, injector layouts, and valve designs, so verifying the correct part number is important before replacement.
Common Cylinder Head Failure Symptoms
- Loss of engine compression
- Coolant leaks or oil contamination
- White exhaust smoke
- Engine overheating
- Cracked cylinder head or warped sealing surfaces
Cylinder head failures may occur due to overheating, gasket failure, improper installation torque, or long-term thermal stress inside the combustion chamber.
Verify Fitment Before You Buy
Cylinder heads vary depending on engine model, CPL configuration, and emissions generation. To confirm compatibility before ordering, provide:
- Engine serial number (preferred)
- CPL number
- Truck year / make / model
- Current cylinder head casting number
- Photos of the cylinder head if available
This information helps ensure the correct Cummins engine cylinder head is selected for your application.
