• Black Nitride (B/L) coating for superior wear resistance and reduced friction
• Race Master construction — designed for high-RPM, high-performance street and track use
• Precision-machined stems for accurate valve guide fit and consistent sealing
• High-temp alloy construction handles the thermal demands of performance HEMI builds

Whether you're building a naturally aspirated street machine or a forced-induction race engine, the Manley 11669B-8 valves deliver the reliability and performance that Manley Performance is known for in the HEMI community.
