Designed to meet the rigorous demands of bracket, drag, and oval track racing, these intake valves deliver exceptional durability and performance for engines operating up to 8000 RPM.

Built for racers and performance enthusiasts alike, these valves enhance airflow and combustion efficiency, helping to unlock the full potential of your HEMI powerplant. Whether upgrading a naturally aspirated or mildly boosted engine, the Manley Race Series valves provide reliable operation under extreme conditions without sacrificing longevity.

Key Features

Manley Race Series intake valves combine advanced materials and precision engineering to ensure superior performance and durability in high-stress racing environments:

• Constructed from high-grade stainless steel for outstanding strength and corrosion resistance
• 1.575-inch valve head diameter optimized for improved airflow and volumetric efficiency
• Precision-machined bead on the valve stem for secure valve spring retention, reducing valve float at high RPM
• Engineered to withstand engine speeds up to 8000 RPM, ideal for bracket, drag, and oval track racing
• Optimized valve face and stem profiles to promote efficient combustion and power delivery
• Compatible with factory valve guides and seats for a direct-fit installation
• Manufactured to tight tolerances ensuring consistent fitment and reliable sealing
• Complete set of 8 valves included for a full intake valve upgrade on V8 engines

Construction & Design

These intake valves are crafted from premium stainless steel, balancing high tensile strength with excellent resistance to heat and wear. The 1.575-inch valve head diameter is carefully designed to maximize airflow into the combustion chamber, improving engine breathing and efficiency.

The bead located on the valve stem ensures secure retention of valve springs, which is critical for maintaining valvetrain stability during high-RPM operation. Manley’s precision machining and heat treatment processes guarantee dimensional stability and durability, even under the extreme thermal and mechanical stresses of racing.

Consistent valve seating and sealing are achieved through meticulous manufacturing standards, helping to maintain compression and prevent power loss during demanding use.

Installation & Fitment

These intake valves are direct replacements for the factory intake valves in 5.7L VVT HEMI V8 engines, fitting seamlessly into the original valve guides and seats without any modifications. Installation is straightforward for experienced engine builders and racers, requiring no cutting, drilling, or special tuning.

Recommended for engines operating up to 8000 RPM, this valve set is ideal for high-performance applications where reliability and durability are paramount.
