Product Details
If you're rebuilding the top end of your Chevy small block engine, you'll want to make sure your exhaust valves can handle the heat and pressure. This Ferrea 6000 Series exhaust valve is built for that job. It's designed to be a direct replacement for your stock valve, but with some key differences that make it a solid option for performance builds.
This particular valve has a 1.625-inch head diameter, which is a common size for Chevy SB applications, and it's made with a strong steel alloy that's known for its durability under high temperatures. The 11/32-inch stem fits standard guides, and the overall length is 4.96 inches. It's also +.050 inches oversized, meaning it's meant to be used with a block that's been machined to accept a slightly larger valve, often done during a performance rebuild to increase airflow. The 12-degree seat angle is also standard for many performance heads.
When you're putting your engine back together, using well-built components like these Ferrea valves can make a real difference in how your engine performs and lasts. Make sure to check your cylinder head specifications to confirm this valve's sizing is appropriate for your specific build.
