551-3880 Cylinder Head Assembly For C7.1 Engine

Optimized Airflow Dynamics: The cylinder head features high-flow intake and exhaust ports, meticulously designed to minimize flow resistance. This ensures superior volumetric efficiency, allowing the engine to breathe deeply for maximum power and torque across a wide RPM range, while also improving exhaust scavenging.

High-Strength, Compacted Graphite Iron (CGI) Construction: Manufactured from advanced materials, the assembly provides exceptional structural integrity and resistance to thermal fatigue and mechanical stress. This robust construction ensures long-term reliability under high-boost and high-load conditions, maintaining precise valve timing and combustion seal.

Integrated Cross-Flow Cooling Jacket: An efficient cooling system with strategically placed coolant passages surrounds the combustion chambers, injector bores, and exhaust ports. This targeted heat management prevents localized hot spots, reduces thermal distortion, and allows for higher power density and improved emission control.

High-Pressure Fuel System Integration: The head is engineered to accommodate and seal the unit's high-pressure fuel injectors directly within its structure. This precise integration is crucial for optimal atomization and combustion efficiency, leading to lower fuel consumption and reduced particulate matter.

Four-Valve-Per-Cylinder Design: By utilizing two intake and two exhaust valves per cylinder, the C7.1 head maximizes the airflow area. This design promotes a more efficient combustion process, enhances turbulence for a cleaner burn, and contributes to the engine's exceptional power-to-weight ratio and responsive performance.

Overhead Camshaft Configuration: The integration of an overhead camshaft (OHC) driven by a gear train ensures precise, direct actuation of the valves. This results in minimal valvetrain inertia, reliable high-RPM operation, and accurate control over valve events for optimal performance and low noise levels.
