Overview:

Manley Performance Race Master Exhaust Valves are precision-engineered components designed specifically for high-performance Chevrolet 5.7L HEMI engines built through 2008. These valves are crafted to withstand the intense demands of bracket racing, drag racing, and oval track competition, making them an excellent choice for serious racers and engine builders.

If you operate an engine running up to 8000 RPM, these valves provide the durability and reliability needed to maintain optimal exhaust flow and valve train stability under extreme conditions. Whether you are building a race-only engine or upgrading your existing valvetrain for improved performance, Manley’s Race Master valves deliver consistent quality and performance.

Key Features:

Manley Race Master Exhaust Valves incorporate advanced design and manufacturing techniques to ensure superior strength and performance. Key features include:

• Bead Loc groove design for enhanced valve spring retention and improved valvetrain stability at high RPM
• 1.575-inch valve head diameter optimized for efficient exhaust gas flow in 5.7L HEMI engines
• Manufactured from high-grade materials to resist wear, heat, and fatigue during demanding race conditions
• Precision ground stems for smooth valve guide fitment and reduced friction
• Engineered specifically for Chevrolet 5.7L HEMI engines through 2008 model year
• Ideal for engines operating up to 8000 RPM, balancing durability with performance
• Set of 8 valves included, sufficient for a complete V8 exhaust valve upgrade

Construction & Design:

These exhaust valves are crafted using rigorous manufacturing standards to meet the high stresses encountered in racing environments. The Bead Loc groove enhances the retention of valve springs, reducing the risk of valve float or spring failure at elevated engine speeds. The 1.575-inch valve head size is optimized to improve exhaust scavenging and flow characteristics, contributing to better engine breathing and efficiency.

Manley’s attention to detail in stem finish and material selection ensures long-lasting durability and consistent performance lap after lap. These valves are designed to fit directly into the factory valve guides of the specified Chevrolet HEMI engines, providing a reliable and precise fitment.

Installation & Fitment:

This set of exhaust valves is designed as a direct replacement for the exhaust valves in Chevrolet 5.7L HEMI engines built through 2008. Installation requires standard engine assembly procedures and 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, provided the engine is prepared for performance components. Professional installation is recommended to ensure correct valve lash and seating.
