If you're rebuilding the top end of your Chevrolet Small Block engine, especially if you're aiming for improved performance or durability, these Ferrea exhaust valves are a solid choice. They're made from a super alloy that's known for its strength and resistance to heat, which is crucial for exhaust valve longevity under demanding conditions. This particular valve has a 1.6-inch head diameter and an 11/32-inch stem, with an overall length of 5.06 inches. It's also +.150 inches oversized, meaning it's designed to fit into a larger valve seat if you're machining your heads for a bigger valve setup.

Ferrea is a well-known name in performance engine components, and these valves reflect that reputation. The super alloy material offers a good balance of strength and heat tolerance, making them suitable for a wide range of applications from street performance to more serious racing builds. When installing, remember that oversized valves require matching valve seats and proper machining of the cylinder head to ensure a perfect seal and optimal performance. This is a single valve, so you'll need to order the correct quantity for all your cylinder head ports.
