Overview:

The AFR 212cc 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 bare cylinder heads are ideal for enthusiasts and builders seeking to maximize power output and reliability on 5.7L through 6.4L Hemi platforms, including high-performance variants like the 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 engines.

Crafted with advanced CNC machining, these heads deliver consistent combustion chamber volumes and optimized intake and exhaust runner shapes, providing a solid foundation for high-performance builds. Whether upgrading a street machine or preparing a race engine, the Black Hawk Gen 3 heads offer a versatile solution that balances power gains with durability.

Key Features:

These cylinder heads incorporate several advanced features to improve engine breathing and overall performance:

• Combustion chamber volume of 69cc, optimized for efficient combustion and power delivery
• Intake runner volume of 212cc with a square port shape for improved airflow
• Exhaust runner volume of 75cc featuring a D-port design for effective exhaust scavenging
• CNC-machined combustion chambers, intake runners, and exhaust runners for precision and consistency
• Intake valve diameter of 2.125 inches and exhaust valve diameter of 1.650 inches for enhanced flow capacity
• Valve guides made from durable bronze material for long-lasting valve stability
• Valve seats machined from ductile iron to withstand high-performance conditions
• Standard intake and exhaust port locations for compatibility with factory components
• Valve stem seals included to maintain proper valve lubrication and reduce oil consumption
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation

Construction & Design:

Manufactured from high-quality cast aluminum, the AFR Black Hawk Gen 3 heads offer a lightweight yet robust solution for performance applications. The use of CNC machining throughout the combustion chamber and port areas ensures precise tolerances and superior airflow characteristics compared to stock heads. Bronze valve guides and ductile iron valve seats provide durability under high-stress conditions, making these heads suitable for both street and track use.

The heads feature a traditional Hemi combustion chamber style with an 18-degree intake valve angle and a 16.5-degree exhaust valve angle, maintaining compatibility with factory valvetrain components. The design supports a maximum valve lift of 0.600 inches, allowing for aggressive camshaft profiles without compromising reliability.

Installation & Fitment:

These cylinder heads are designed to fit most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat & Trackhawk engines. Installation requires standard procedures for Hemi cylinder heads and may necessitate valve train component upgrades depending on the intended use and camshaft specifications. The heads are sold bare, so intake and exhaust valves, valve springs, retainers, rocker arms, and other valvetrain components must be sourced separately to complete the build.

What's Included:

• One bare AFR Black Hawk Gen 3 Hemi cylinder head
• Valve stem seals

Ideal For:

This product is perfect for engine builders and performance enthusiasts looking to upgrade their Hemi engines for increased airflow and power potential. It suits street performance builds, drag racing, road racing, and other motorsport applications where reliable, high-flow cylinder heads are essential. The bare head format allows for customization with aftermarket valves, springs, and valvetrain components to tailor the setup to specific performance goals.
