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

When you're building a high-performance Small Block Chevrolet engine, especially one that's going to see a lot of time at high RPMs, every ounce of weight savings in the valvetrain makes a difference. This kit from Manley Performance includes eight titanium exhaust valves, specifically designed to help your engine rev higher and more freely. Titanium is significantly lighter than traditional steel, which reduces the stress on your valve springs and other valvetrain components, allowing for improved efficiency and durability at extended high-rpm operation.

Manley makes these valves from a special titanium alloy that balances strength, hardness, and ductility for high-temperature environments, indicated by the 'HT' in the part number. They're forged as a single piece, which creates a stronger part with better grain flow compared to valves that are welded together. The machining is done on advanced CNC equipment to ensure they meet very precise dimensions, with tight tolerances for consistent performance. Each valve also features an inserted hard tip to handle the rocker arm contact and Manley's unique Bead Loc keeper groove, which helps secure the valve in place.

This set is intended for 'All Pro' Small Block Chevrolet applications and includes eight exhaust valves. You'll want to ensure your cylinder heads are set up to accept these specific dimensions: a 1.625-inch head diameter and a 0.3110-inch stem diameter, with an overall length of 5.950 inches. Each valve weighs in at a mere 72 grams, showcasing the significant weight reduction you achieve with this kit.
