Ferrea Chevy/Chry/Ford SB 1.65in 11/32in 5.14in 0.29in 15 Deg +.200 Ti Comp Exhaust Valve - Set of 8

This set includes eight Ferrea Competition Plus exhaust valves, specifically designed for Chevy, Chrysler, and Ford small-block V8 engines. Each valve features a 1.65-inch face diameter and a 0.375-inch (11/32-inch) stem diameter, with an overall length of 5.14 inches. The +.200 dimension indicates these valves are 0.200 inches longer than standard, which can be beneficial for certain camshaft profiles or cylinder head modifications, allowing for improved geometry and valve train clearance.

Crafted from high-quality titanium alloy, these valves offer a notable advantage in terms of weight reduction compared to steel valves. This lower mass means less stress on the valve springs and camshaft, allowing for higher engine speeds and improved responsiveness. The titanium construction also provides excellent resistance to heat and wear, crucial for exhaust valves that endure extreme temperatures and combustion forces. The 15-degree valve seat angle is a common specification that ensures a good seal against the valve seat.

When rebuilding or modifying a performance small-block engine, especially one intended for higher RPM operation or forced induction, these Ferrea valves are a solid option. Their advanced material and precise dimensions contribute to a more robust and efficient valvetrain. Ensure you have the correct valve spring pressures and retainers to match the valve weight and operating conditions for optimal performance and longevity.
