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, Manley's Titanium Exhaust Valve Kit is a serious consideration. These valves are specifically crafted to reduce the overall weight in your valve train, which is crucial for allowing your engine to spin faster and more reliably at extended high engine speeds. This weight reduction also helps improve overall engine efficiency.

Manley builds these valves from a single piece of forged titanium, a process that ensures exceptional durability and eliminates potential weak points often found in welded designs. They are then meticulously machined on advanced CNC equipment to maintain very precise tolerances, ensuring they seal perfectly and perform optimally. The titanium alloys used are chosen for their specific balance of hardness, ductility, and fatigue strength, especially at the high temperatures exhaust valves encounter. The 'HT' designation means they are made from high-temperature material, and they also feature inserted hard tips for added durability.

This kit includes 8 exhaust valves, each weighing in at a mere 87 grams, with a head diameter of 1.625 inches and a stem diameter of 0.3415 inches. Manley's rigorous quality control process means you're getting a set of valves that meet the highest precision standards, ready for demanding applications where every ounce and every RPM counts.
