This cylinder head offers enthusiasts and performance builders a reliable way to increase airflow and durability while maintaining compatibility with many factory components. Ideal for street performance and mild racing applications, it enhances engine breathing and combustion efficiency without requiring extensive modifications.
Crafted to fit the stock intake manifold, exhaust manifold, valve covers, rockers, spark plugs, and accessories, this cylinder head also supports Hellcat components, making it a versatile choice for those looking to improve power and reliability on their Gen III HEMI 5.7L platform.
Key Features:
The Edelbrock Performer RPM cylinder head incorporates advanced design elements to optimize performance and durability:
- Fully CNC machined combustion chambers for precise and consistent airflow
- CNC profiled intake and exhaust port bowls and entries/exits to improve volumetric efficiency
- Cast from high-quality A356 aluminum and heat treated to T6 specifications for strength and longevity
- Reinforced combustion chambers and rocker bosses to withstand increased cylinder pressures
- Extra material added around intake and exhaust ports to facilitate porting for racing applications
- Intake and exhaust port flanges remain in factory locations for seamless OEM component compatibility
- Valves tipped away from bore walls to unshroud larger valves while maintaining factory geometry
- Increased valve seat diameters for improved heat transfer and durability over stock heads
- Machined for use on either driver or passenger side of the engine block
Construction & Design:
The Performer RPM cylinder heads are precision cast from A356 aluminum alloy, known for its excellent strength-to-weight ratio and thermal conductivity. Each head undergoes a T6 heat treatment process to enhance material hardness and durability under high-stress conditions. Manufactured and assembled at Edelbrock’s Torrance, California facility, these heads meet strict quality control standards to ensure consistent performance and fitment.
The CNC machining process refines the combustion chambers and port geometry to maximize airflow and combustion efficiency. Reinforcements in critical areas such as the rocker bosses and combustion chambers provide added strength to handle increased cylinder pressures, making these heads suitable for performance upgrades without sacrificing reliability.
Installation & Fitment:
The Edelbrock Performer RPM Aluminum Cylinder Head is designed as a direct bolt-on replacement for 2003–2008 Gen III HEMI Early 5.7L engines. It fits with the stock intake manifold, exhaust manifold, valve covers, rockers, spark plugs, and accessories, minimizing the need for additional modifications. The heads are machined for installation on either the driver or passenger side, simplifying the upgrade process.
For those seeking to maximize performance, pairing these heads with the Edelbrock Victor EFI #7179 intake manifold provides an optimized combination for improved airflow and power gains.
What's Included:
