Overview:

The AFR 212cc Black Hawk Gen 3 Hemi Cylinder Heads are precision-engineered performance components designed to enhance power and efficiency for a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines. Crafted from durable cast aluminum, these heads are ideal for enthusiasts seeking improved airflow, combustion efficiency, and reliability in their 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 Hemi-powered vehicles. Whether upgrading a street machine or building a high-performance race engine, these heads deliver consistent results with a focus on quality and durability.

These cylinder heads are fully assembled and ready to install, offering a direct fit for most Gen 3 Hemi engines without the need for extensive modifications. Their advanced design supports hydraulic roller camshafts and features CNC-machined combustion chambers and ports for optimized airflow and combustion.

Key Features:

Engineered for maximum performance and reliability, the AFR Black Hawk Gen 3 Hemi heads include:

• 212cc intake runner volume for improved air charge and throttle response
• 69cc CNC-machined combustion chambers designed for efficient, powerful combustion
• Square intake port shape and D-port exhaust design for optimized flow dynamics
• 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 for stable valve control up to 0.600-inch lift
• Titanium retainers and 10-degree valve locks for durability under high RPM conditions
• Bronze valve guides and ductile iron valve seats for long-lasting wear resistance
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation
• Fully assembled with intake and exhaust valves, valve springs, retainers, locks, and valve stem seals included

Construction & Design:

Manufactured from high-quality cast aluminum, the AFR Black Hawk Gen 3 heads combine lightweight construction with exceptional strength and heat dissipation. The heads feature CNC-machined combustion chambers, intake runners, and exhaust runners to ensure precise port shapes and smooth airflow paths. This meticulous machining process enhances volumetric efficiency and promotes consistent combustion, contributing to improved power output and fuel economy.

The valve seats are crafted from ductile iron for superior durability, while bronze valve guides provide excellent wear resistance and heat tolerance. The inclusion of titanium retainers reduces valvetrain mass, allowing for higher RPM capability and improved valve control. Designed specifically for hydraulic roller camshafts, these heads maintain reliable valvetrain geometry and performance under demanding conditions.

Installation & Fitment:

The AFR Black Hawk Gen 3 Hemi Cylinder Heads are designed as direct replacements for most 5.7L, 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 Hemi engines found in Chrysler, Dodge, Jeep, and Ram vehicles from 2005 onward. Installation requires standard procedures for cylinder head replacement and is compatible with factory valve covers and pushrods sized at 5/16 inch. No modifications to the intake or exhaust port locations are necessary, ensuring a straightforward upgrade path.

While rocker arms, studs, nuts, and guideplates are not included, these heads accept standard Gen 3 Hemi valvetrain components. Proper torque specifications and assembly techniques should be followed to ensure optimal sealing and performance.

What's Included:

• Fully assembled cast aluminum cylinder head
• Intake valves (2.125 inch diameter)
• Exhaust valves (1.650 inch diameter)
• Dual valve springs per valve
• Titanium retainers
• Valve locks (10-degree style)
• Valve stem seals
• Bronze valve guides and ductile iron valve seats

Ideal For:

These cylinder heads are perfect for performance enthusiasts and engine builders looking to upgrade their Gen 3 Hemi engines for street, strip, or light racing applications. They provide a balanced combination of improved airflow, durability, and compatibility with factory components, making them suitable for naturally aspirated builds as well as forced induction setups. Whether you are restoring a muscle car, building a modern performance truck, or enhancing a Jeep’s off-road power, the AFR Black Hawk Gen 3 heads offer a reliable foundation for increased horsepower and torque.
