Designed to meet the rigorous demands of bracket, drag, and oval track racing, these intake valves deliver enhanced durability and reliability for high-performance applications. Whether you are building a race engine or upgrading your factory valvetrain, this valve set offers superior strength and precision to handle aggressive cam profiles and elevated cylinder pressures.

These valves provide improved valve control and longevity, ensuring consistent engine performance at high RPMs up to 8,000. They are an ideal choice for racers and performance enthusiasts seeking to maximize airflow and efficiency while maintaining dependable operation under extreme conditions.

Key Features

Manley Performance Race Master Intake Valves incorporate advanced engineering and premium materials to optimize performance and durability:

• 2.000-inch valve head diameter precisely matched to 5.7L HEMI intake ports for maximum airflow and volumetric efficiency
• Bead Loc groove design enhances valve retention and stability, preventing valve float during high RPM and heavy load conditions
• Constructed from high-strength, heat-resistant materials to withstand the intense thermal and mechanical stresses of racing environments
• Precision ground valve stems ensure smooth fitment within factory valve guides, reducing friction and wear
• Compatible with factory valve springs and retainers for straightforward installation without modifications
• Engineered to perform reliably at engine speeds up to 8,000 RPM
• Ideal for use with aggressive camshaft profiles and high cylinder pressures common in performance builds

Construction & Design

These intake valves are manufactured with meticulous attention to detail, utilizing premium alloys selected for their exceptional heat resistance and mechanical strength. The critical Bead Loc groove design securely locks the valve spring retainer in place, eliminating the risk of valve float and ensuring precise valve timing during high-RPM operation.

Each valve is precision ground to exacting tolerances, promoting optimal sealing and smooth movement within the valve guides. This careful engineering reduces wear on both the valve and guide, contributing to extended engine life even under the demanding conditions of competitive racing.

Installation & Fitment

The Manley Race Master Intake Valve Set is a direct replacement for the intake valves in 2003–2008 5.7L HEMI engines. These valves fit standard factory valve guides and retainers, allowing for a straightforward installation process without the need for cutting, drilling, or special tuning. This ensures a hassle-free upgrade for performance enthusiasts and engine builders looking to enhance their valvetrain strength and reliability.
