You’re not alone. It all begins with a 21-4N stainless steel valve that is black nitrided for an unprecedented combination of core strength and surface friction reduction. Even at high rpms these springs hold a tight seal so your valves won’t flutter or float even after seasons of being heavy on the throttle.
