Manley Titanium Exhaust Valve Kit for Small Block Chevrolet AFR Eliminator Heads

This kit includes a set of eight Manley Performance titanium exhaust valves, specifically made for Small Block Chevrolet engines using AFR Eliminator cylinder heads. These valves are designed to significantly reduce weight in your valve train, which is crucial for engines that need to spin at high RPMs or are subjected to extended periods of high-speed operation. The one-piece forged construction, featuring grain flow, ensures these valves are built tough and are less prone to failure than welded alternatives.

Manley uses advanced titanium alloys chosen for their balance of strength, hardness, and ductility at high temperatures, making them durable even under demanding conditions. Each valve is precisely machined on state-of-the-art CNC equipment to very tight tolerances, ensuring they perform optimally. The valves have inserted hard tips and use Chevy LS-style keeper grooves. It's important to note that while AFR heads typically have guides sized at .3147 inches, these Manley valves have a .3135-inch stem. Manley strongly recommends checking and properly sizing your valve guides to ensure the correct clearance for these specific valve stems.

These valves are a solid choice for anyone building a performance engine that will see frequent high-RPM use. You'll want to use Manley valve locks, part numbers 13098-16 or 13153-16, depending on your spring and retainer setup. The overall length is 5.080 inches, the head diameter is 2.125 inches, and each valve weighs in at 92 grams.
