Description

The Manley Performance 11397-1 is a Severe Duty exhaust valve designed for high-temperature gasoline engines. It is crafted from XH-428 material for superior tensile strength at elevated temperatures. The valve features a chrome stem, hard tip, and a swirl-polished under-head area for enhanced durability and airflow.

These valves have undergone rigorous fatigue testing, enduring up to 100,000,000 cycles at 40,000 psi and 1400°F, significantly outperforming competitors. The fully machined combustion face contributes to improved combustion efficiency.
