Overview:

The AFR 185cc 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. These heads are ideal for enthusiasts and builders seeking a reliable upgrade that supports increased power potential while maintaining strong street manners and durability. Crafted to fit 5.7L, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines, these cylinder heads offer a versatile solution for performance builds ranging from mild to aggressive applications.

Whether upgrading a factory engine or building a custom powerplant, the Black Hawk Gen 3 heads provide a solid foundation for improved volumetric efficiency and throttle response. Their design balances airflow capacity with combustion chamber shape to optimize power delivery across the RPM range.

Key Features:

These AFR cylinder heads incorporate advanced design elements and quality materials to deliver consistent performance gains:

• 185cc intake runner volume for enhanced airflow and improved mid-to-high RPM power
• 69cc combustion chamber volume with classic Hemi hemispherical chamber design for efficient combustion
• Cast aluminum construction for lightweight strength and superior heat dissipation
• Square intake port shape and D-port exhaust design to maximize flow characteristics
• Intake valve diameter of 2.050 inches and exhaust valve diameter of 1.590 inches for optimal valve sizing
• Bronze valve guides and ductile iron valve seats for durability and long service life
• Valve stem seals included to reduce oil consumption and improve valve train reliability
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for easy installation
• Designed for use with 5/16 inch pushrods and 10-degree valve locks for secure valve retention

Construction & Design:

The AFR Black Hawk Gen 3 heads are cast from high-quality aluminum alloy, providing an excellent strength-to-weight ratio and superior thermal conductivity. This helps maintain optimal operating temperatures and reduces the risk of detonation under high-performance conditions. The heads feature precision-machined valve seats and guides, ensuring accurate valve alignment and smooth operation. Although the combustion chambers and ports are not CNC-machined, the design leverages AFR’s extensive flow testing and development to deliver consistent, reliable performance.

The hemispherical combustion chamber promotes efficient air-fuel mixture burning, contributing to improved power output and throttle response. The intake and exhaust ports maintain a standard location and shape, allowing compatibility with most stock and aftermarket components without extensive modification.

Installation & Fitment:

These cylinder heads are designed as direct replacements for a broad range of Chrysler, Dodge, Jeep, and Ram Hemi engines, including the 5.7L, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk variants. Installation typically requires standard procedures for cylinder head replacement, with no special machining or modifications necessary. The heads are sold individually and intended for the driver side, so be sure to order accordingly for a complete set.

Valve springs, rocker arms, retainers, locks, and other valve train components are not included, allowing builders to customize their valve train setup to match their specific performance goals.

What's Included:

• One bare AFR Black Hawk Gen 3 Hemi cylinder head (driver side)
• Valve stem seals
• Valve guides
• Valve seats machined and ready for valves (valves not included)

Ideal For:

This cylinder head is perfect for enthusiasts and professional builders upgrading or rebuilding Chrysler, Dodge, Jeep, or Ram Hemi engines who want a reliable, high-quality head that supports increased airflow and power potential. It suits street performance builds, mild to moderate race applications, and those seeking a solid foundation for further engine modifications.
