    Ferrea light weight valves in stock and on SALE

    Guy's, i have 5 sets of these lightweight valves in stock and ready to ship.
    Normal wait time for these was 3 weeks. This is a complete set of 12 valves.

    I have also marked them down 10%

    Would it be safe to run these with stock springs at 8500 rpm? I assume since they are lighter valves you would not need heavier springs. Is this correct?

    This is correct in most cases but i would at least run the RR retainers/shims. If you are going to run 8800 or more RPM's then you will also want the Riva valve train upgrade.

    Valves are not really a performance enhancement. These are just light weight which will enable you to turn more RPM's safely without dropping a valve and destroying your motor.
