Manley Titanium Exhaust Valve Kit - Small Block Chevrolet - All Pro

When you're rebuilding the top end of your Small Block Chevrolet and aiming for serious performance, especially in high-RPM situations, you'll want to look at this Manley Titanium Exhaust Valve Kit. This kit includes eight exhaust valves, each crafted from high-quality titanium alloys. Titanium is chosen here because it's significantly lighter than traditional steel valves, which helps reduce the overall weight of your valve train. This weight reduction is crucial for allowing your engine to spin faster and more reliably at high revolutions per minute, making it a popular choice for racing applications or any build pushing the limits.

What sets these valves apart is their construction. Manley uses a one-piece forged process with careful grain flow management, which creates a stronger, more durable valve compared to those made with welded heads. They're then precisely machined on advanced CNC equipment to ensure they meet very tight tolerances. This meticulous machining process is key to ensuring each valve seals properly and performs consistently, even under the stress of extended high-RPM operation. The 'HT' in the part number signifies that these valves are made from high-temperature material, giving them added durability in demanding conditions. You'll also find that each valve comes with an inserted hard tip and Manley's unique Bead Loc single radius keeper groove, designed for secure installation.

This kit is designed for performance builds where reducing mass and handling high engine speeds are priorities. The set includes eight exhaust valves, each weighing in at approximately 71 grams, with a head diameter of 1.600 inches and a stem diameter of 0.3110 inches. They measure 5.950 inches in overall length. Remember to consult your engine builder or service manual for specific installation procedures and any other components you might need for your rebuild.
