Overview:

The AFR 224cc Black Hawk Gen 3 Hemi Cylinder Heads are precision-engineered performance components designed to enhance airflow and combustion efficiency for a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines. Crafted from durable cast aluminum, these bare cylinder heads are ideal for enthusiasts and builders seeking to maximize power potential on 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 Hemi platforms.

Featuring CNC-machined combustion chambers and intake/exhaust runners, these heads deliver consistent quality and improved flow characteristics. The Black Hawk Gen 3 heads are perfect for high-performance street builds, track applications, or any project requiring reliable, high-flow cylinder heads that maintain the classic Hemi combustion chamber design.

Key Features:

These cylinder heads incorporate advanced design elements to optimize engine performance and durability:

• 224cc intake runner volume with square port shape for enhanced airflow
• 73cc CNC-machined Hemi combustion chambers for efficient combustion
• 75cc D-port exhaust runners CNC-machined for improved exhaust flow
• Intake valve diameter of 2.165 inches and exhaust valve diameter of 1.650 inches
• Cast aluminum construction for lightweight strength and heat dissipation
• Hydraulic roller camshaft compatibility with maximum valve lift of 0.600 inches
• Bronze valve guides and ductile iron valve seats for durability and heat resistance
• Valve stem seals included to maintain valve train integrity
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled
• Standard intake and exhaust port locations with 18° intake and 16.5° exhaust valve angles

Construction & Design:

Manufactured from high-quality cast aluminum, the AFR Black Hawk Gen 3 heads offer a perfect balance of strength and weight savings. The heads feature fully CNC-machined combustion chambers, intake runners, and exhaust runners to ensure precise tolerances and optimal flow dynamics. Bronze valve guides and ductile iron valve seats provide excellent wear resistance and thermal stability, essential for high-performance applications.

The heads are designed with a traditional Hemi combustion chamber style, maintaining the iconic hemispherical shape that promotes efficient air-fuel mixture burning. The inclusion of valve stem seals helps reduce oil consumption and maintain valve train reliability over extended use.

Installation & Fitment:

These cylinder heads are designed to fit most Chrysler, Dodge, Jeep, and Ram Hemi engines with displacements ranging from 5.7L to 6.4L, including the 6.1L SRT8 and 6.2L Hellcat variants. Installation requires standard procedures for aftermarket heads and may necessitate compatible gaskets, valve train components, and tuning adjustments to optimize performance. The heads are sold bare, so intake and exhaust valves, springs, retainers, and rocker arms must be sourced separately.

What's Included:

• One bare AFR Black Hawk Gen 3 cast aluminum cylinder head
• Valve stem seals installed

Ideal For:

These cylinder heads are ideal for performance enthusiasts, engine builders, and racers looking to upgrade their Hemi engines for improved airflow and combustion efficiency. They suit street performance builds, drag racing, road racing, and other motorsport applications where reliable power gains and durability are essential. The heads provide a solid foundation for custom camshaft profiles and high-lift valve trains.
