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 vehicles equipped with 5.7L to 6.4L Hemi engines. These cast aluminum heads deliver enhanced airflow and combustion efficiency, making them an excellent upgrade for enthusiasts seeking improved power and throttle response without extensive modifications.

Built to accommodate hydraulic roller camshafts and featuring CNC-machined intake and exhaust runners, these heads optimize volumetric efficiency while maintaining reliable street and track performance. Ideal for both naturally aspirated and forced induction setups, the Black Hawk Gen 3 heads provide a solid foundation for high-performance builds.

Key Features:

These cylinder heads incorporate advanced design and manufacturing techniques to maximize engine output and durability:

• 212cc intake runner volume and 75cc exhaust runner volume for improved airflow
• 73cc CNC-machined combustion chambers with classic Hemi hemispherical design
• Square intake port shape and D-port exhaust for optimized flow dynamics
• Large 2.125-inch intake valves and 1.650-inch exhaust valves for enhanced breathing
• Dual valve springs with titanium retainers and 10-degree locks for stable valve control up to 0.600-inch lift
• Cast aluminum construction for lightweight strength and efficient heat dissipation
• Bronze valve guides and ductile iron valve seats for long-lasting durability
• Comes assembled with intake and exhaust valves, valve springs, retainers, locks, and valve stem seals included
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation

Construction & Design:

The AFR Black Hawk Gen 3 heads are crafted from high-quality cast aluminum, providing a strong yet lightweight solution that helps reduce overall engine weight. The combustion chambers, intake runners, and exhaust runners are CNC-machined to exacting tolerances, ensuring consistent airflow and combustion efficiency across all cylinders.

The hemispherical combustion chamber design promotes efficient fuel burn and power delivery, while the bronze valve guides and ductile iron seats enhance component longevity under high-performance conditions. Dual valve springs with titanium retainers maintain valve stability at high RPMs, supporting aggressive camshaft profiles without valve float.

Installation & Fitment:

These cylinder heads are designed as direct replacements for most 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 variants. Installation requires standard procedures for cylinder head replacement and is compatible with hydraulic roller camshafts. No modifications to intake or exhaust port locations are necessary, making them a straightforward upgrade for enthusiasts looking to improve performance while maintaining factory compatibility.

What's Included:

• Assembled cylinder head with cast aluminum body
• Intake valves (2.125-inch diameter)
• Exhaust valves (1.650-inch diameter)
