Ferrea Chevrolet SB 1.6in 11/32in 5.06in 12 Deg S-Flo +.150 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 S-Flo exhaust valves. These are designed to handle the demands of a performance rebuild, ensuring your engine breathes efficiently.

These valves are made from a super alloy material, which is known for its strength and resistance to high temperatures found in performance engines. The 1.6-inch diameter helps with airflow, while the 11/32-inch stem fits standard guides. They measure 5.06 inches in overall length and feature a 12-degree seat angle. The +.150 dimension indicates they are 0.150 inches longer than stock, which can be important for valve train geometry when using certain camshafts or cylinder heads. This set includes eight valves, enough for a complete V8 engine.
