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, reducing internal friction and weight is key to unlocking higher RPMs and better power. These Manley Titanium Exhaust Valves are specifically designed to help you achieve that goal. By using titanium, Manley significantly cuts down on the reciprocating mass in your valve train, which is crucial when you're pushing the engine to its limits.

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 than those made with welded heads, which can be a weak point under stress. Manley machines these valves with advanced CNC equipment to very tight tolerances, ensuring they seal perfectly and perform reliably. They use special titanium alloys chosen for their balance of hardness, ductility, and fatigue strength, especially at the high temperatures found in performance engines. Plus, they come with a CrN Slick Coating for improved durability and a Bead Loc? groove for secure installation.

This kit includes eight 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. They are ready for demanding, high-RPM applications where every ounce of weight savings and every bit of durability counts.
