Ferrea Chevrolet SB 1.6in 7mm 5.55in 0.29in 24 Deg Tulip +.600 Super Alloy Exhaust Valve - Set of 8

If you're rebuilding the top end of your Chevrolet Small Block engine, especially for performance applications, you'll want to consider these Ferrea Super Alloy Exhaust Valves. These valves are built to handle the heat and stress that come with higher compression and more aggressive camshaft profiles. The 1.6-inch diameter is a common size for many SB applications, and the 7mm stem helps reduce weight and friction.

Ferrea uses a special Super Alloy material for these exhaust valves, which is known for its ability to resist high temperatures and resist burning, a common failure point for standard valves under heavy use. The 5.55-inch overall length and the 24-degree tulip face are designed to work with many common cylinder head port designs and valve seat configurations. The +.600 measurement indicates they are a longer valve, often used to achieve specific valve lift or geometry with aftermarket camshafts and rocker arms.

This set includes eight valves, enough for a complete V8 engine. When installing, pay close attention to valve guide clearance and ensure your valve springs are matched to the camshaft's requirements to get the most out of these well-built components.
