Overview:

The AFR 185cc Black Hawk Gen 3 Hemi Cylinder Heads are precision-engineered performance upgrades designed for a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L to 6.4L Hemi engines. Crafted from durable cast aluminum, these heads deliver improved airflow and combustion efficiency, making them an excellent choice for enthusiasts seeking enhanced power and reliability without extensive modifications.

Ideal for street performance, mild racing, and high-performance builds, these cylinder heads offer a balanced combination of flow capacity and valve sizing to optimize engine breathing and responsiveness. Whether upgrading a 5.7L Hemi or a high-output 6.2L Hellcat, the Black Hawk Gen 3 heads provide a solid foundation for increased horsepower and torque.

Key Features:

These cylinder heads incorporate several advanced features to maximize performance and durability:

• 185cc intake runner volume with square port design for efficient airflow
• 69cc combustion chamber volume optimized for Hemi-style combustion
• Intake valves measuring 2.050 inches and exhaust valves at 1.590 inches for improved valve flow
• Dual valve springs with stainless steel retainers and 10-degree locks for reliable valve control up to 0.600 inch lift
• Cast aluminum construction for lightweight strength and excellent heat dissipation
• Standard intake and exhaust port locations with D-port exhaust shape for compatibility with factory manifolds
• Bronze valve guides and ductile iron valve seats for long-lasting durability
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation
• Includes intake and exhaust valves, valve springs, retainers, locks, and valve stem seals for a complete assembly

Construction & Design:

Manufactured from high-quality cast aluminum, the AFR Black Hawk Gen 3 heads combine lightweight construction with robust durability. The design maintains the classic Hemi combustion chamber shape, promoting efficient flame propagation and power output. Bronze valve guides and ductile iron valve seats ensure longevity under high-performance conditions, while the dual valve springs and stainless steel retainers provide stable valve operation at elevated RPMs.

The heads are assembled with precision, including all critical valvetrain components except rocker arms and studs, allowing builders to customize their valvetrain setup. The intake and exhaust ports are designed for compatibility with most factory and aftermarket manifolds, simplifying installation and integration into existing engine platforms.

Installation & Fitment:

These cylinder heads are designed to fit a broad range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 engines. Installation typically requires no major modifications, as the heads retain standard port locations and valve cover mounting styles. They are sold individually, allowing for flexible engine build configurations.

While the heads come fully assembled with valves, springs, retainers, locks, and seals, additional components such as rocker arms and studs must be sourced separately. Proper torque specifications and break-in procedures should be followed to ensure optimal performance and longevity.

What's Included:

• Cast aluminum cylinder head (assembled)
• Intake valves (2.050 inch diameter)
• Exhaust valves (1.590 inch diameter)
• Dual valve springs per valve
• Stainless steel retainers
• 10-degree valve locks
