Manley Performance Race Master Exhaust Valves are precision-engineered for Chevrolet 5.7L HEMI engines produced from 2003 through 2008. Designed to meet the rigorous demands of bracket racing, drag racing, and oval track competition, these valves offer exceptional durability and reliability for high-RPM applications up to 8000 RPM. Whether you are building a dedicated race engine or upgrading your existing valvetrain, Manley’s Race Master valves provide consistent performance and longevity under extreme conditions.
These valves are an ideal choice for racers and engine builders who require robust exhaust components that maintain optimal flow and valvetrain stability during intense operation. Their advanced design ensures your engine breathes efficiently while withstanding the stresses of competitive motorsports.
Manley Race Master Exhaust Valves incorporate advanced engineering and high-quality materials to deliver superior strength and performance. Key features include:
These exhaust valves are manufactured to exacting standards to endure the high stresses of racing environments. The Bead Loc groove enhances valve spring retention, ensuring stable valvetrain operation and minimizing spring failure risks at elevated engine speeds. The 1.575-inch valve head size is carefully optimized to improve exhaust scavenging and flow characteristics, contributing to better engine breathing and overall efficiency.
Manley’s meticulous attention to stem finish and material selection guarantees long-lasting durability and consistent performance lap after lap. These valves fit directly into the factory valve guides of the specified Chevrolet 5.7L HEMI engines, providing a precise and reliable fitment without the need for modifications.
This set of Manley Race Master Exhaust Valves is designed as a direct replacement for the exhaust valves in Chevrolet 5.7L HEMI engines manufactured from 2003 to 2008. Installation follows standard engine assembly procedures, requiring proper valve spring and retainer setup to match the Bead Loc groove design.
No modifications to the cylinder head or valve guides are necessary when installing these valves, assuming the engine is prepared for performance components. Professional installation is recommended to ensure correct valve lash, seating, and optimal valvetrain operation.
Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
