• Intake valves measuring 2.165 inches and exhaust valves at 1.650 inches for enhanced breathing
• Dual valve springs with titanium retainers and 10-degree locks for reliable valve control up to 0.600 inch lift
• CNC-machined intake and exhaust runners plus combustion chambers for precision and consistency
• Cast aluminum construction for lightweight strength and heat dissipation
• Includes intake and exhaust valves, valve springs, retainers, locks, and valve stem seals for a complete valve train upgrade
• Valve guides made from durable bronze with ductile iron valve seats for long-lasting performance
• Standard intake and exhaust port locations with perimeter bolt valve cover mounting

Construction & Design:

The AFR Black Hawk Gen 3 cylinder heads are constructed from high-quality cast aluminum, providing an excellent balance of strength and weight savings. The heads feature fully CNC-machined combustion chambers and runners, ensuring precise tolerances and optimal airflow characteristics. Bronze valve guides and ductile iron valve seats contribute to durability and heat resistance, while the titanium retainers reduce valvetrain mass for improved valve control at high RPM.

These heads are designed with a traditional Hemi combustion chamber layout, featuring an 18-degree intake valve angle and 16.5-degree exhaust valve angle to maximize volumetric efficiency. The dual valve spring setup supports aggressive camshaft profiles with up to 0.600 inch valve lift, making these heads suitable for a wide range of performance builds.

Installation & Fitment:

The AFR Black Hawk Gen 3 heads are a direct fit for most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L, 6.1L SRT8, 6.4L 392, 6.2L Hellcat, and Trackhawk Hemi engines. Sold individually for the driver side, these heads install using standard hardware and require no major modifications for proper fitment. They retain the factory intake and exhaust port locations, allowing compatibility with many aftermarket and OEM components.

While rocker arms, rocker arm studs, and nuts are not included, the heads are machined to accept standard 5/16 inch pushrods and perimeter bolt valve covers. This ensures a straightforward installation process for experienced mechanics and enthusiasts upgrading their Hemi powerplants.

What's Included:

• One assembled Black Hawk Gen 3 cylinder head (driver side)
• Intake valves
• Exhaust valves
• Dual valve springs
• Titanium retainers
• 10-degree valve locks
• Valve stem seals
• Bronze valve guides

Ideal For:

The AFR Black Hawk Gen 3 heads are perfect for enthusiasts building high-performance Hemi engines for street, strip, or off-road use. They suit those seeking a reliable, high-flow cylinder head upgrade that supports aggressive camshafts and increased displacement. Whether upgrading a factory 5.7L Hemi or building a 6.4L 392 or Hellcat-based powerplant, these heads provide a solid foundation for enhanced horsepower and torque while maintaining durability and drivability.
