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

If you're building a high-performance small block engine for GM, Ford, or Chrysler, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to shave critical weight off your valve train, which is essential when you're pushing your engine to higher RPMs. Reducing that reciprocating mass helps the engine rev more freely and can improve overall efficiency and durability under stress.

What sets these apart is their one-piece forged construction. This method ensures a solid, consistent grain flow throughout the valve, making it stronger and less prone to failure than valves that are welded together. Manley uses specific titanium alloys chosen for their balance of hardness, ductility, and fatigue strength, especially at the high temperatures exhaust valves endure. They're then machined to very tight tolerances on advanced CNC equipment, ensuring each valve performs exactly as it should. The inserted hard tips add even more durability where it counts.

This set includes 8 exhaust valves, each weighing about 74 grams, with a 1.625-inch head diameter and a 5.060-inch overall length. They are made from high-temperature material, indicated by the 'HT' designation, and are available with either conventional square keeper grooves or Manley's Bead Loc single radius grooves. These are a well-built component for anyone serious about getting the most out of their engine build.
