Manley Titanium Exhaust Valve Kit - Big Block Chevrolet - M&M X20

This kit includes eight Manley Titanium Exhaust Valves, specifically designed for Big Block Chevrolet engines with the M&M X20 configuration. These valves are crafted from exceptional titanium alloys, striking a balance between mechanical properties, hardness, ductility, and fatigue strength at high temperatures. The primary advantage of using titanium is significant weight reduction in the valve train, which directly contributes to improved engine efficiency and allows for higher engine speeds, making them suitable for aggressive camshaft profiles and extended high-rpm operation.

Manley's one-piece forged construction with grain flow ensures durability and minimizes potential weak points, unlike head-welded alternatives. Each valve is meticulously machined in state-of-the-art CNC turning centers and valve stem grinders, maintaining exacting tolerances for optimal performance. These valves feature Manley's unique Bead Loc? single radius keeper grooves, which are essential for secure installation. It's important to note that tip protection is required for these valves.

The rigorous quality control process, including stringent final inspections and delivery within tight tolerances, ensures uncompromising quality, performance, and reliability. This kit is a solid option for those looking to optimize their engine for high-performance applications where reducing reciprocating mass is critical.
