Dart severe-duty stainless steel valves are designed to withstand the pressures of high-lift roller cams and feature a head design that promotes high flow. They are constructed of high-strength stainless steel that is backcut just enough for flow, without sacrificing strength. They feature swirl-polished heads with hard chrome stems.
