Manley Titanium Exhaust Valve Kit - Small Block - ASCS and Wissota

If you're building a high-performance small block engine for ASCS or Wissota racing, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to help your engine rev higher and more freely by significantly cutting down on the weight of the valve train. This isn't just about shaving a few ounces; it's about allowing your engine to achieve and sustain higher RPMs, which is crucial for competitive racing.

What sets these valves apart is their one-piece forged construction. This method, combined with careful grain flow management, creates a stronger, more durable valve compared to those made with head-welded alternatives. Manley uses specific titanium alloys chosen for their balance of hardness, ductility, and fatigue strength at the high temperatures these engines can reach. They're then precisely machined on state-of-the-art CNC equipment to ensure they meet very tight tolerances. You'll also notice they come with a CrN Slick Coating, inserted hard tips for durability, and Manley's own Bead Loc? keeper groove system.

This kit includes a set of 8 exhaust valves, each measuring 1.600 inches in head diameter, with a 0.3110-inch stem diameter and an overall length of 5.140 inches. The rigorous quality control Manley puts these valves through means you're getting a reliable component ready for demanding applications.
