Detroit Diesel Cylinder Heads Catalog

At the heart of every Detroit Diesel engine lies the cylinder head—a critical component that controls airflow, houses the valves, and seals combustion pressure. A properly functioning cylinder head ensures reliable ignition, efficient fuel burn, and maximum power output. When cylinder heads wear, crack, or lose sealing capability, engines suffer from poor compression, higher fuel consumption, and reduced reliability.

Diesel Pro Power supplies aftermarket Detroit Diesel cylinder heads and related components trusted by over 40,000 satisfied customers in more than 180 countries. Whether you operate a 53 Series in a fishing vessel, a 71 Series in a tugboat, a 92 Series in a generator, a 149 Series in offshore equipment, or a modern Series 60 in industrial service, our catalog provides the parts you need to keep your engine running at peak performance.

Why Cylinder Heads Matter in Detroit Diesel Engines

Core Functions of the Cylinder Head

• Airflow Management: Controls the intake of fresh air and exhaust gas removal.

• Valve Seating: Houses intake and exhaust valves, springs, and guides.

• Combustion Sealing: Maintains compression by sealing the top of the combustion chamber.

• Fuel & Injector Integration: Provides a mounting point and precise fit for injectors.

• Cooling Passages: Circulates coolant around hot zones to prevent overheating.

Common Signs of Cylinder Head Failure

• White smoke from the exhaust due to coolant leaks.

• Loss of compression or power.

• Cracks between valve seats from overheating.

• Excessive oil consumption from worn valve guides and seals.

• Coolant and oil mixing inside the head.
