Suitable for mild performance cams up to 275 duration. These springs offer increased pressure to reduce valve float at higher RPM's, while eliminating coil bind issues with high lift camshafts and/or high ratio rocker assemblies. They also offer increased safety in the event of spring breakage. Viton (.530) valve seals required. Set includes 12 valve springs with dampers. Retainers and seals sold separately. May require machining of the valve seats and guides.
