Key Features:

These cylinder heads incorporate advanced CNC machining and thoughtful design elements to optimize airflow and durability:

• 224cc intake runner volume with square port shape for improved air velocity and flow
• 75cc exhaust runner volume with D-port design for efficient exhaust scavenging
• 73cc CNC-machined hemispherical combustion chambers for superior combustion efficiency
• Large 2.165-inch intake valves and 1.650-inch exhaust valves for increased airflow capacity
• Hydraulic roller camshaft compatibility with maximum valve lift of 0.600 inches
• Bronze valve guides and ductile iron valve seats for enhanced durability and heat resistance
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for easy installation
• Valve stem seals included to ensure proper sealing and longevity
• Machined intake and exhaust runners for consistent performance and fitment
• 10-degree lock style for secure valve retention

Construction & Design:

Manufactured from high-quality cast aluminum, the AFR Black Hawk Gen 3 heads are engineered for strength and lightweight performance. The heads feature fully CNC-machined combustion chambers, intake runners, and exhaust runners, ensuring precise tolerances and optimal airflow dynamics. The use of bronze valve guides and ductile iron valve seats enhances wear resistance and thermal stability, critical for high-performance applications.

The hemispherical combustion chamber design promotes efficient fuel-air mixing and combustion, contributing to improved power output and throttle response. Additionally, the heads are designed with standard intake and exhaust port locations, making them compatible with most factory and aftermarket components.

Installation & Fitment:

These cylinder heads are sold as bare units and are compatible with Chrysler, Dodge, Jeep, and Ram Hemi engines ranging from 5.7L to 6.4L, including the 6.1L SRT8, 6.2L Hellcat, and 6.4L 392 models. Installation requires standard machining and assembly procedures typical for performance cylinder heads. Valve springs, retainers, locks, rocker arms, and rocker arm nuts are not included and must be sourced separately to match your camshaft and valve train setup.

The heads feature a perimeter bolt valve cover mounting style and are drilled for accessory bolt holes, facilitating straightforward installation with existing hardware. No modifications to the oiling system or heat crossover are necessary, as these heads utilize a through-pushrod oiling design and do not include steam holes or O-ring machining.
