Product Details
This set includes eight Manley Severe Duty Series stainless steel exhaust valves, each measuring 1.600 inches. These valves are specifically crafted for Small Block Chevy V8 engines, designed to handle the demands of high-temperature gasoline applications.
Manley uses XH-428 material for these exhaust valves, a material that offers nearly double the tensile strength at 1500°F compared to other common exhaust valve materials. They feature chrome stems and hard tips for added durability, along with swirl-polished under-head areas and fully machined faces to help improve airflow and combustion efficiency. These valves have undergone rigorous fatigue testing, enduring up to 100 million cycles at 40,000 psi and 1400°F, which is significantly longer than many competitor valves.
If you're rebuilding or working on the top end of a high-performance Small Block Chevy, these valves are built to last under demanding conditions.
