About this part

Product Details

If you're rebuilding the top end of your 1997-2004 Chevrolet Corvette, these Manley Race Flo intake valves are a solid option. They're built for engines that see a lot of action, typically under 8000 RPM, making them a popular choice for bracket, drag, and oval track racing applications. Manley uses stainless steel for both intake and exhaust valves, which is a smart move for durability. These intake valves feature chrome stems and hard tips, adding to their wear resistance and overall lifespan.

What really helps these valves perform is the swirl-polished treatment on the under-head areas and the fully machined combustion faces. This design work is all about optimizing airflow into the cylinder and making sure combustion is as efficient as possible. The Race Flo shape is specifically designed for certain engine builds, so it's worth checking if it matches your setup. You're getting a set of 8 valves here, which is what you'll need for a V8.
