Overview:

The AFR Street Hawk CNC Gen 3 Hemi 195cc Bare Cylinder Head (Right) is engineered for enthusiasts and professional builders seeking a high-performance upgrade for their Chrysler, Dodge, Jeep, or Ram Hemi engines. Designed specifically for the passenger side (right) cylinder head, this bare head offers a precision-machined platform to maximize airflow and combustion efficiency. It is ideal for those building or upgrading 5.7L, 6.1L SRT8, 6.4L 392, 6.2L Hellcat, and Trackhawk engines who want to enhance power potential while maintaining reliability.

With a focus on CNC-machined accuracy, this cylinder head delivers consistent combustion chamber volumes and optimized intake and exhaust runner shapes. It provides a solid foundation for custom valve and valvetrain components, allowing for tailored performance builds.

Key Features:

This bare cylinder head combines advanced CNC machining with durable materials and a design optimized for Hemi engines. Key features include:

• Combustion chamber volume of 69cc for efficient combustion and power delivery
• 195cc intake runner volume with square port shape for improved airflow
• 64cc exhaust runner volume with D-port shape to enhance exhaust scavenging
• CNC-machined combustion chamber, intake runner, and exhaust runner for precision and consistency
• Cast aluminum construction for lightweight strength and heat dissipation
• Hydraulic roller camshaft compatibility with standard intake and exhaust port locations
• Valve guides made of bronze for durability and smooth valve operation
• 5-angle valve seats machined from ductile iron for reliable sealing and longevity
• Valve stem seals included to protect valve stems and reduce oil consumption
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation

Construction & Design:

The AFR Street Hawk CNC Gen 3 Hemi cylinder head is crafted from high-quality cast aluminum, providing an excellent balance of strength, weight savings, and thermal management. The CNC machining process ensures that the combustion chambers, intake runners, and exhaust runners are precisely shaped to optimize airflow and combustion efficiency. Bronze valve guides and ductile iron valve seats enhance durability and maintain tight tolerances under high-performance conditions. The natural finish preserves the raw aluminum look while allowing for customization or coating if desired.

Designed specifically for Hemi engines, the intake and exhaust ports maintain standard locations and angles (18° intake, 16.5° exhaust) to ensure compatibility with existing manifolds and valvetrain components. This bare head is engineered to accept hydraulic roller camshafts and is machined for through-pushrod oiling, supporting reliable valvetrain operation in demanding applications.

Installation & Fitment:

This cylinder head is sold as a bare right-side (passenger side) unit and requires assembly with valves, springs, retainers, rocker arms, and other valvetrain components. It fits a wide range of Chrysler, Dodge, Jeep, and Ram Hemi engines, including 5.7L, 6.1L SRT8, 6.4L 392, 6.2L Hellcat, and Trackhawk models. Installation typically involves standard cylinder head replacement procedures, but professional assembly and tuning are recommended to maximize performance and reliability.

Before purchasing, verify fitment with your specific vehicle and engine combination to ensure compatibility. This product includes mechanical and electrical failure coverage for added peace of mind.
