Overview:

The AFR 212cc Black Hawk Gen 3 Hemi cylinder heads are precision-engineered performance components designed to fit a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines, including the 5.7L, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk models. Crafted for enthusiasts and professional builders seeking to maximize airflow and combustion efficiency, these heads deliver improved power potential and throttle response while maintaining reliable operation.

Built with cast aluminum for lightweight strength and durability, these heads feature CNC-machined combustion chambers and intake/exhaust runners to optimize flow characteristics. The Black Hawk Gen 3 heads are ideal for street performance, racing, and high-output applications where enhanced breathing and valve control are critical.

Key Features:

Designed to elevate your Hemi engine’s performance, the AFR Black Hawk Gen 3 heads include a host of advanced features:

• 212cc intake runner volume for improved airflow and volumetric efficiency
• 73cc CNC-machined Hemi combustion chambers for precise combustion and power gains
• Square intake port shape and D-port exhaust design for optimized air/fuel mixture flow
• Intake valves measuring 2.125 inches and exhaust valves at 1.650 inches for enhanced breathing
• Dual valve springs with 1.290-inch outer diameter and 0.600-inch maximum valve lift capability
• Titanium retainers and 10-degree valve locks for high RPM durability
• Bronze valve guides and ductile iron valve seats for long-lasting wear resistance
• Fully assembled heads including intake and exhaust valves, valve springs, retainers, locks, and valve stem seals
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation

Construction & Design:

The AFR Black Hawk Gen 3 cylinder heads are cast from high-quality aluminum alloy, providing an excellent strength-to-weight ratio that reduces overall engine weight without sacrificing durability. Each head undergoes CNC machining to ensure exact combustion chamber volumes and port shapes, delivering consistent performance and fitment.

The Hemi-style combustion chambers are designed to promote efficient flame propagation and reduce detonation risk, while the square intake ports and D-shaped exhaust ports maximize airflow velocity and turbulence control. Bronze valve guides and ductile iron seats enhance longevity under demanding conditions, and the inclusion of titanium retainers reduces valvetrain mass for improved valve control at high RPM.

Installation & Fitment:

These cylinder heads are engineered as direct-fit replacements for most Chrysler, Dodge, Jeep, and Ram Hemi engines in the 5.7L to 6.4L range, including the 6.1L SRT8 and 6.2L Hellcat & Trackhawk variants. Installation requires standard procedures for cylinder head replacement and may necessitate compatible gaskets and hardware. No modifications to the intake or exhaust ports are typically needed due to the heads’ standard port locations.

Note that rocker arms, rocker arm studs, nuts, and guideplates are not included and must be sourced separately. The heads are sold individually and are designated for the driver side.

What's Included:

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

Ideal For:

This cylinder head is perfect for performance enthusiasts, engine builders, and racers looking to upgrade their Hemi engines for increased airflow, higher RPM capability, and improved combustion efficiency. Whether building a street/strip machine, a drag racing engine, or a high-performance daily driver, the AFR Black Hawk Gen 3 heads provide a solid foundation for power and reliability.

AFR (Air Flow Research) is a performance cylinder-head manufacturer known for CNC-ported designs and application-specific head packages for popular engine platforms. Their products are built for airflow efficiency and repeatable performance, making them a go-to upgrade for street/strip builds and serious competition engines alike.
