What is the main benefit of using titanium valves?

The primary advantage of titanium valves is their significantly lower weight compared to steel. This reduction in mass helps decrease valve train stress, allowing for higher engine speeds and improved overall engine efficiency.

What type of keeper groove do these valves use?

These Manley titanium valves feature an OE-style single radius keeper groove. You will need to use specific Manley valve locks, such as P/N 13098-16 (7 degree) or 13153-16 (10 degree), depending on your spring and retainer choice.

Are these valves suitable for stock engines?

While these valves are built for high-RPM applications and aggressive camshafts, their lightweight nature and precise machining can offer benefits even in modified engines that see frequent high-speed operation. Always consult with your engine builder for specific application recommendations.

About this part

Product Details

These Manley titanium intake valves, with a 2.205-inch head diameter and a 0.3135-inch stem diameter, are forged from exceptional titanium alloys. This material choice is key to their performance, offering a significant reduction in valve train weight. This weight savings directly translates to improved engine efficiency and allows the engine to rev higher and more freely, making them a solid choice for high-RPM applications and aggressive camshaft profiles.

Manley builds these valves as a single piece, using a forging process that incorporates grain flow. This method creates a stronger, more durable valve compared to alternatives that might use head-welding. They are then meticulously machined on advanced CNC equipment, ensuring they meet very precise tolerances. This attention to detail in manufacturing is crucial for optimal valve performance and reliability, especially when the engine is pushed to its limits. The titanium alloys selected strike a good balance of hardness, ductility, and fatigue strength needed for high-temperature engine environments.

Each set of eight valves undergoes a strict final inspection to guarantee uncompromising quality and performance. These valves feature an OE-style single radius keeper groove, and you'll need to use Manley valve locks like P/N 13098-16 (7 degree) or 13153-16 (10 degree), depending on your spring and retainer setup.
