Increasing valve spring pressure helps the valvetrain and control valve float at higher RPM’s. It’s also necessary when going to higher lift camshafts. This set of springs is made to handle just over 0.600″ valve lift. The kit includes new springs and locks. Original retainers can be used with them.Valve springs can be installed without removing the heads from the engine.
