Manley Titanium Exhaust Valve Kit - Small Block GM, Ford, Chrysler

If you're rebuilding the top end of a small block GM, Ford, or Chrysler engine and pushing the limits with high-RPM operation, these Manley Titanium Exhaust Valves are worth a serious look. They're designed to significantly cut down on the weight of your valvetrain, which is crucial when you're aiming for higher engine speeds and need the components to keep up reliably. This reduction in mass helps everything move more freely and reduces stress on other parts.

What sets these valves apart is their one-piece forged construction. Unlike some other designs that might use welding, this forging process creates a solid, durable part with excellent grain flow, minimizing potential failure points. Manley uses special titanium alloys that are chosen for their balance of strength, hardness, and ductility, specifically for the high temperatures exhaust valves endure. They're then machined with very tight tolerances on advanced CNC equipment, ensuring each valve performs exactly as it should. The 'HT' suffix means they use high-temperature material, and they also feature inserted hard tips for added durability where it counts.

This kit includes 8 exhaust valves, each weighing in at a mere 74 grams, with a head diameter of 1.625 inches and a 0.3415-inch stem diameter. They are designed for applications that demand precise valvetrain control at extended high-RPM ranges, often pairing well with aggressive camshaft profiles. When you're building an engine for serious performance, every gram saved and every component's reliability matters, and these valves are built to meet those demands.
