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 spin faster and more reliably at elevated speeds. This also helps improve overall engine efficiency and responsiveness when you're really working the engine hard.

What sets these apart is their one-piece forged construction. This method, combined with careful grain flow management, creates a stronger, more durable valve compared to designs that weld the head to the stem. Manley uses specific titanium alloys chosen for their balance of hardness, ductility, and fatigue strength at the high temperatures found in the exhaust port. They're then meticulously machined on advanced CNC equipment to exacting tolerances, ensuring each valve seals perfectly and performs consistently. This attention to detail means you get a valve that's not only lightweight but also built to last under demanding conditions.

This kit includes a set of 8 exhaust valves, each weighing in at just 79 grams, with a 1.625-inch head diameter and a 5.560-inch overall length. They are made to tight tolerances, and Manley puts them through a rigorous final inspection to ensure you're getting a reliable component for your build. If you're aiming for maximum performance and durability in a high-revving application, these titanium valves are a well-built choice.
