What is the primary application for these Manley Race Series valves?

These Manley Race Series valves are designed for performance engines operating under 8000 RPM. They are particularly well-suited for bracket, drag, and oval track racing applications where durability and airflow are critical.

What makes the stainless steel construction beneficial?

The stainless steel construction offers excellent durability and resistance to heat and stress, which is important for high-performance engines. The chrome stems and hard tips further improve wear resistance, extending the life of the valves.

Are these valves suitable for alcohol-fueled engines?

While these are intake valves, Manley recommends their stainless steel exhaust valves for alcohol engines due to their ability to withstand the specific demands of those fuels. These intake valves are still a robust choice for high-performance gasoline applications.

About this part

Product Details

If you're rebuilding the top end of your Dodge Hemi Gen III 5.7L and pushing the limits, Manley's Race Series intake valves are a solid choice. These are built for engines that see a lot of action, especially those running up to 8000 RPM, making them ideal for bracket, drag, or oval track racing applications. They're designed to handle the stress and heat that come with performance builds.

These intake valves are made from a durable stainless steel that holds up well under demanding conditions. The stems are chrome-plated and the tips are hardened, which helps them resist wear over time, especially with frequent valve lift. Manley also swirl polishes the under-head areas and fully machines the combustion faces. This attention to detail helps improve airflow into the cylinder and can contribute to better combustion efficiency. The Race Flo shape is specifically designed to optimize flow for certain racing engine configurations.

This set includes 8 intake valves, each measuring 2.020 inches in diameter. They also feature a bead lock groove, which is important for ensuring the valve seat stays securely in place under high stress. If you're working on a performance Hemi, these valves are a well-built component that can help you achieve your engine's potential.
