Manley Performance Race Master Exhaust Valves are precision-engineered components designed specifically for the demanding conditions of high-performance Chrysler 6.4L HEMI engines from 2012 to 2014. Built to endure the extreme heat and stress of bracket racing, drag racing, and oval track competition, these valves provide the durability and reliability essential for serious racers and engine builders. Whether you are assembling a new race engine or upgrading an existing setup, Manley’s Race Master valves ensure consistent valve timing and sealing at engine speeds up to 8000 RPM.
With Manley’s reputation for quality and performance, these exhaust valves are a trusted upgrade that enhances exhaust flow and valve longevity, helping maximize engine efficiency and durability under intense racing conditions.
Manley Race Master Exhaust Valves incorporate advanced design and materials to meet the rigorous demands of high-performance Chrysler 6.4L HEMI engines. Key features include:
Manley Race Master Exhaust Valves are crafted using advanced metallurgy and precision machining techniques to ensure superior strength and durability. The valves feature a robust design that resists wear, thermal fatigue, and deformation, which are critical factors in maintaining performance and reliability in high-RPM race engines.
The 2.180-inch head diameter is specifically optimized for Chrysler 6.4L HEMI cylinder heads, providing excellent sealing and efficient exhaust gas evacuation. Each valve undergoes rigorous quality control inspections to guarantee dimensional accuracy and a smooth surface finish, contributing to longer service life and consistent valve operation under demanding conditions.
These valves are designed as direct replacements for the 2012–2014 Chrysler 300 6.4L 392 HEMI engines and fit the factory cylinder heads without any modifications. Installation follows standard engine assembly procedures and valve train setup, requiring no cutting, drilling, or special tuning. They are compatible with OEM valve guides and seats, making them an ideal choice for professional engine builders and experienced enthusiasts upgrading or rebuilding race engines.
This valve set is perfect for:
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!
