2526

Overview:

The AFR Street Hawk CNC Gen 3 Hemi 195cc Cast Aluminum Cylinder Head is engineered for enthusiasts and professional builders seeking a high-performance upgrade for Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L to 6.4L Hemi engines. Designed to deliver improved airflow and combustion efficiency, this cylinder head enhances power potential while maintaining street-friendly drivability. Its precision CNC-machined combustion chambers and intake/exhaust runners optimize volumetric efficiency, making it an ideal choice for naturally aspirated and forced induction applications alike.

Whether you are upgrading a 5.7L Hemi or pushing the limits of a 6.4L 392 or Hellcat engine, the AFR Street Hawk offers a reliable and durable solution that supports aggressive camshaft profiles and higher valve lifts without sacrificing reliability.

Key Features:

Built with advanced CNC machining and premium materials, the AFR Street Hawk cylinder head boasts several key features that contribute to its performance and longevity:

• 195cc intake runner volume with square port design for optimized airflow
• 69cc CNC-machined combustion chambers featuring the iconic Hemi hemispherical design
• 64cc D-port exhaust runners for efficient exhaust gas evacuation
• Cast aluminum construction for lightweight strength and superior heat dissipation
• Includes intake valves (2.050" diameter) and exhaust valves (1.590" diameter) for precise sealing and durability
• Dual valve springs with titanium retainers and 10-degree locks for high RPM stability
• Hydraulic roller camshaft compatibility with a maximum valve lift of 0.600 inches
• Bronze valve guides and 5-angle ductile iron valve seats for extended wear resistance
• Perimeter bolt valve cover mounting style with accessory bolt holes drilled for ease of installation

Construction & Design:

The AFR Street Hawk cylinder head is crafted from high-quality cast aluminum, combining lightweight properties with exceptional strength and thermal conductivity. Every combustion chamber, intake runner, and exhaust runner is CNC-machined to exacting tolerances, ensuring consistent airflow and combustion efficiency across all cylinders. The hemispherical combustion chamber design promotes a more complete and efficient burn, improving power output and throttle response.

Durability is enhanced through the use of bronze valve guides and ductile iron valve seats, which provide excellent wear resistance under high-performance conditions. The dual valve spring setup with titanium retainers supports aggressive cam profiles and high valve lifts, reducing valve float and increasing reliability during spirited driving or track use.

Installation & Fitment:

This cylinder head is designed as a direct fit replacement for the passenger side (right) cylinder head on most Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.4L 392, and 6.2L Hellcat or Trackhawk engines. Installation requires standard mechanical skills and tools, with no major modifications necessary. The head is assembled and ready to install, but rocker arms, studs, and nuts are not included and must be sourced separately.

Ensure compatibility by verifying your vehicle’s engine and model year before purchase. This part is sold individually and covers the passenger side cylinder head only.

What's Included:

• Fully assembled cast aluminum cylinder head (passenger side/right)
• Intake valves (2.050" diameter)
• Exhaust valves (1.590" diameter)
• Dual valve springs per valve with titanium retainers
• Valve locks (10-degree style)
• Valve stem seals
• Valve guides (bronze)
• Valve seats machined with 5-angle ductile iron design
• Accessory bolt holes drilled

Ideal For:

This cylinder head is perfect for performance enthusiasts, engine builders, and racers looking to upgrade their Hemi-powered vehicles for improved airflow, combustion efficiency, and valve train stability. It suits naturally aspirated builds as well as forced induction setups, making it a versatile choice for street, strip, or track applications. The AFR Street Hawk is especially beneficial for those running aggressive camshafts and seeking to maximize the potential of their 5.7L to 6.4L Hemi engines.
