GSC Dual Conical Valve Spring and Ti Retainer Set EJ No.2 Gasket These short blocks feature 14mmKEEP YOUR VALVES UNDER CONTROL GSC's dual conical valve springs. Using a varying coil diameter as well as coil spacing offers a superior damping of valve spring harmonics even compared to beehive springs. Dampening the transfer of valvetrain shock reduces stress and increases the life of components. Dual springs provide increased valve opening range before coil bind, increased heat dissipation, and extended life vs. an equivalent single spring.
