Product Details
If you're rebuilding the top end of your Chevy Big Block engine and need exhaust valves that can handle serious use, these Manley Race Master valves are a solid option. They're built for engines running up to 8000 RPM, making them a great choice for bracket, drag, or oval track racing applications.
These valves are made from stainless steel, which is known for its durability. The stems are chrome-plated and feature hard tips to resist wear, and the under-head areas are swirl-polished to help improve airflow into the cylinder. The combustion faces are also fully machined for better efficiency. Manley recommends these specifically for exhaust valves in alcohol-fueled engines, where they've proven to be reliable.
This set includes eight exhaust valves, and they are the straight-stem Race Master style, which is a common choice for many performance builds.
