Starting with a 1.625-inch face diameter and a 4.96-inch overall length, these Ferrea 6000 Series exhaust valves are built for Chevy small-block engines. The 12-degree seat angle is a common choice for performance builds, helping to create a solid seal and efficient gas flow when paired with the right valve seat. This set includes eight valves, enough for a complete V8 engine.

Ferrea uses their 6000 Series alloy for these valves, which is a well-known material in performance circles for its strength and heat resistance. The valves are also +.050 inches oversized on the stem, measuring 11/32 inch, which is important to note if you're rebuilding or modifying your cylinder heads. This sizing is designed to work with specific guides and setups, so always confirm compatibility with your build plans.

When you're putting together a performance engine, the details matter. These Ferrea valves are a solid option for anyone looking to get the most out of their Chevy SB cylinder heads, offering a good balance of material strength and precise dimensions for reliable operation.
