Ferrea Chevy SB 1.6in 11/32in 5.06in 20 Deg Semi Tulip S-Flo +.150 6000 Series Exh Valve - Set of 8

If you're rebuilding the top end of your Chevy small block engine, especially for performance applications, you'll want to make sure your exhaust valves can handle the heat and pressure. These Ferrea 6000 Series exhaust valves are built for that kind of work. They're designed to help your engine breathe better, which is key for making good power.

Ferrea uses high-quality steel for these valves, and they're made with a semi-tulip head design that's a bit more advanced than a standard flat head. This shape helps improve airflow into the cylinder. The valves measure 1.6 inches across the head and have a 5.06-inch overall length with an 11/32-inch stem diameter. This set includes eight valves, enough for a complete V8 engine. They are also +.150 inches longer than stock, which can be useful for certain head porting or camshaft combinations.

When you're putting these in, pay attention to the valve seat contact pattern to ensure a good seal. Ferrea is a well-known name in performance engine components, and these valves are a solid option for anyone looking to get the most out of their Chevy small block.
