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 a serious consideration. They're designed to significantly cut down on valve train weight, which is crucial for allowing your engine to rev higher and more freely. This weight reduction also helps improve overall engine efficiency and responsiveness, especially when you're deep into the powerband.

What sets these valves apart is their one-piece forged construction. This method ensures a solid, durable part with consistent grain flow, avoiding potential weak spots you might find in other designs. Manley machines these valves with very tight tolerances using advanced CNC equipment, ensuring they perform exactly as intended. They're made from special titanium alloys chosen for their balance of strength, hardness, and ductility at high temperatures, which is critical for exhaust valves that endure a lot of heat. Each valve also features an inserted hard tip for added durability.

This kit includes a set of 8 exhaust valves, each weighing in at a mere 74 grams. The head diameter is 1.600 inches, with a 0.3415-inch stem diameter and an overall length of 4.960 inches. They are available with conventional square keeper grooves or Manley's Bead Loc single radius keeper grooves. These are built for demanding applications where every ounce of weight savings and high-RPM capability matters.
