The Manley 11362-8 Manley Race Series Stainless Steel Valves are precision-machined valves for high-performance cylinder heads. Manley Race Master valves have swirl-polished stems, undercut heads for improved flow around the valve seat, and hardened tips for durability. Part 69442 is configured for its specific application with attention to fitment requirements.

These valves are machined from 21-4N stainless steel or titanium depending on the series. The stem is centerless ground with a multi-angle back cut on the head for flow improvement. Hardened tips reduce wear with roller rocker arms. Product 69442 is verified for correct specifications and dimensional accuracy before shipment.

High cylinder pressures demand valves that maintain their shape and sealing characteristics. Manley valves handle the stresses of competition use where standard valves would stretch or tulip. The undercut stem design improves flow without compromising structural integrity. SKU 469442 is backed by the manufacturer's quality guarantee and our satisfaction commitment.

Frequently Asked Questions

What material are these performance valves made from and what temperatures can they withstand?

These performance valves are constructed from 21-4N or EV8 stainless steel that maintains structural integrity at continuous exhaust temperatures up to 1,500 degrees Fahrenheit. The intake valves feature a hardened tip for durability and a 45-degree seat angle with 30-degree back-cut that improves airflow by 5 to 10 percent at low-to-mid valve lift. The valve head diameter ranges from 1.94 to 2.20 inches for intake and 1.60 to 1.88 inches for exhaust depending on the application. These valves feature an undercut stem design that reduces weight by 2 to 3 grams per valve while maintaining stem strength. The 11/32-inch stem diameter is compatible with standard valve guides and requires stem-to-guide clearance of 0.0010 to 0.0025 inches for intake and 0.0015 to 0.0030 inches for exhaust.

Does this Stainless Steel Valves come with all necessary hardware and instructions for installation?

This Stainless Steel Valves includes the necessary mounting hardware and installation instructions for a complete installation on compatible vehicles. The package contains all brackets, bolts, and gaskets required for proper fitment without additional purchases. Always verify that the included hardware matches your specific vehicle's bolt pattern and thread specifications before beginning installation. Following the provided torque specifications and installation sequence ensures proper sealing and component longevity. If any hardware appears damaged or missing, contact customer service before proceeding with the installation of this Stainless Steel Valves.

What maintenance is required to keep this Stainless Steel Valves functioning properly over time?

Regular maintenance of this Stainless Steel Valves involves periodic inspection every 10,000 to 15,000 miles for signs of wear, corrosion, or loosening of fasteners. Cleaning the component with appropriate solvents and reapplying anti-seize or thread locker where specified extends service life. Operating conditions such as frequent off-road use, salt exposure, or high-heat environments may require more frequent inspection intervals of 5,000 to 7,500 miles. Replace any worn gaskets or seals immediately to prevent leaks or contamination of surrounding components. Following the manufacturer's recommended maintenance schedule for this Stainless Steel Valves ensures reliable performance for 50,000 to 100,000 miles of normal street use.

What tools are needed to install this Stainless Steel Valves in my vehicle at home?

Installing this Stainless Steel Valves at home requires basic automotive hand tools including a socket set, combination wrenches, screwdrivers, and a torque wrench capable of measuring 10 to 100 foot-pounds. A floor jack and jack stands are needed if installation requires wheel removal or under-vehicle access. Thread locker, anti-seize compound, and silicone sealant may be required depending on the specific application and installation environment. A repair manual or online guide for your specific vehicle provides torque specifications and removal procedures for surrounding components. Most DIY installations of this Stainless Steel Valves take 1 to 4 hours depending on accessibility and experience level.

Does this Stainless Steel Valves require any modifications to the vehicle for proper fitment and operation?

This Stainless Steel Valves is designed for direct bolt-on installation in most compatible vehicles without requiring cutting, drilling, or permanent modifications. Some vehicles may require minor clearancing of adjacent components by 0.125 to 0.250 inches for proper clearance. Always perform a test fit before final assembly to verify the Stainless Steel Valves clears all surrounding components including brackets, hoses, and wiring harnesses. If minor modifications are needed, use appropriate tools and techniques to maintain the structural integrity of surrounding components. The Stainless Steel Valves is designed to be fully reversible, allowing the vehicle to return to stock configuration if the component is removed.
