Product Details
Manley Performance is well-known for making strong engine components, and their Severe Duty? Valves are a prime example of that commitment. These intake valves are specifically made for Chevy LS-7 small block engines, designed to handle the demands of high-temperature gasoline applications. If you're rebuilding the top end of your LS-7, these valves offer a well-built option that stands up to rigorous use.
What sets these valves apart is the material: they're crafted from NK-844, a material Manley states has over four times the ultimate tensile strength of competing intake valve materials at 1000?F. They also feature chrome stems and hard tips for added durability, along with swirl-polished under-head areas and fully machined combustion faces. This design helps improve airflow and combustion efficiency, making them a solid choice for performance builds.
This set includes eight intake valves, enough for a complete engine. For optimal performance and longevity, always refer to the manufacturer's installation instructions and ensure proper valve seating during assembly.
