Cylinder Heads for Detroit Diesel 6-71 Turbo

Rebuilt Bare Cylinder Heads

Rebuilt bare cylinder heads for the 6-71 Turbo are fully machined and restored to OEM tolerances. These heads are supplied without valves or springs, making them ideal for rebuilders or technicians who want to customize internal components for specific applications. Each rebuilt head undergoes inspection, pressure testing, and machining to ensure proper sealing, durability, and airflow performance.

New Bare Cylinder Heads

Brand-new cylinder heads are an excellent choice for operators who prefer zero-hour components. These heads are supplied without internal hardware, giving operators the flexibility to install new or upgraded valve assemblies. Manufactured to exact Detroit Diesel specifications, these heads offer a long service life, especially in turbocharged applications where combustion pressures and temperatures are higher.

New Cylinder Heads with Valves and Springs

For customers seeking convenience and a ready-to-install option, complete cylinder heads with valves and springs pre-installed are available. These assemblies reduce downtime and ensure proper valve clearances and spring tension right out of the box. They are offered in both U valve configurations for standard duty and J valve designs for high-performance turbocharged setups.

Complete Cylinder Head Assemblies

For maximum convenience, Diesel Pro Power provides complete cylinder head assemblies that include valves, springs, retainers, seals, and all necessary components. These are particularly popular for marine operators who need a quick turnaround to minimize downtime during vessel maintenance.

Cylinder Head Gasket Kits for 6-71 Turbo

A proper seal between the cylinder head and block is critical for maintaining compression and preventing coolant or oil leaks. Head gasket kits for the 6-71 Turbo include all required seals, gaskets, and washers for a complete installation. Kits are designed for both natural and turbocharged versions of the 71 Series, ensuring compatibility and reliability in high-stress environments.

Valves and Related Components

Exhaust Valves

Exhaust valves for the 6-71 Turbo are engineered to withstand extreme heat and pressure. Available in both U valveconfigurations for standard-duty engines and J valve designs for turbocharged, high-performance engines, these valves ensure efficient exhaust flow and durability under heavy load.

Valve Seals

Valve seals prevent oil leakage into the combustion chamber while maintaining proper lubrication of the valve stems. For turbocharged engines, maintaining a tight seal is critical for preventing oil fouling and ensuring efficient combustion.

Valve Guides

Valve guides maintain precise alignment of the valve stems, ensuring consistent operation under extreme conditions. For the 6-71 Turbo, high-quality guides are available that reduce wear, extend valve life, and improve sealing performance.

Valve Springs and Retainers

Valve springs ensure proper valve closure and timing during high-RPM operation. Turbocharged applications require heavy-duty springs to maintain proper seat pressure and avoid valve float. Retainers and spring washers provide secure seating and prevent movement under load.

Valve Seats

Valve seat inserts provide a durable sealing surface for the valves, resisting wear from combustion gases and high-temperature operation. For marine and industrial turbocharged 6-71 engines, precision-machined valve seats are critical to maintaining compression and extending cylinder head life.

Cylinder Head Fasteners and Accessories

Head Bolts

High-strength head bolts secure the cylinder head to the engine block, maintaining the critical seal provided by the head gasket. Turbocharged engines require precise torque application, and high-quality bolts ensure even clamping pressure across the cylinder head.

Plug Kits

Head plug kits for the 6-71 Turbo include freeze plugs and other sealing components needed to complete head installation. These plugs help maintain proper coolant circulation and prevent leaks.

Valve Covers

Valve covers protect the rocker arm and valve assemblies from contaminants while retaining engine oil. Available in used, refurbished, and new options, Diesel Pro Power offers covers with oil filler openings and breathers, suitable for both 6-71 and 12V71 engines.

Breather Elements and Seals

Breather elements allow crankcase ventilation, reducing pressure buildup inside the valve cover. Proper seals ensure no oil leaks occur at the breather connections, which is essential for clean and efficient operation.

Rocker Arm and Valve Train Components

Rocker Arms

Rocker arms convert camshaft motion into valve actuation. Both left-hand and right-hand rocker arms are available for the 6-71 Turbo, along with injector rocker arms designed for precise fuel delivery. Turbocharged applications require rocker arms in excellent condition to maintain timing and reduce wear.

Rocker Arm Shafts and Brackets

Rocker shafts support the rocker arms and allow smooth pivoting during operation. Brackets hold the rocker assembly securely in place. Replacements ensure that the valve train operates quietly and efficiently, even under heavy turbocharged loads.

Push Rods and Retainers

Push rods transmit camshaft movement to the rocker arms. For the 6-71 Turbo, heavy-duty push rods, springs, and retainers are designed to handle the increased stresses of turbocharged operation.

Cam Followers and Guides

Cam followers transfer motion from the camshaft to the push rods. Guides and retainers ensure proper alignment and reduce wear, providing consistent operation over thousands of hours.

Fuel and Injector Components Related to the Cylinder Head

Injector Tubes

Injector tubes provide a leak-free passage for fuel delivery. Turbocharged engines rely on precise injector performance, and high-quality tubes prevent fuel leaks and combustion inefficiency.

Fuel Jumpers and Connectors

Fuel jumper lines (short and long) connect injectors and allow fuel distribution across the cylinder head. Both old-style and new-style jumper lines are available, along with connectors, elbows, and seals for a complete installation.

Injector Tools

Specialized tools, such as flaring dies and injector line sockets, are available for maintenance. These tools allow technicians to properly install or recondition injector tubes, ensuring reliable performance.

Cooling and Gasket Components

Water Manifold Gaskets

Water manifold gaskets seal the coolant passages between the cylinder head and water manifold. Proper sealing prevents coolant leaks and maintains consistent engine temperature, critical for turbocharged 6-71 performance.

Head-to-Manifold Gaskets

Gaskets between the cylinder head and exhaust manifold prevent leaks of combustion gases. Turbocharged engines operate at higher pressures, making high-quality gaskets essential.

Rocker Cover Gaskets

Available in both old-style black rubber and new-style gray rubber, rocker cover gaskets provide a leak-free seal between the valve cover and cylinder head.
