This new Valve Spring Kit for Ford’s 7.3L Godzilla engine utilizes COMP Cams® Conical Valve Springs to provide .675†of valve lift. The conical springs use round wire featuring a diameter and progressive pitch-driven natural frequency. This design increases the valve train RPM while reducing resonance concerns and decreasing dynamic spring oscillations. The result is longer spring life and the ability to run a more aggressive camshaft. It utilizes chromemoly steel retainers and stock valve seals.
