    new style 918s are supposed to be rated above .600 lift if my memory serves me right. I'm running a .59x cam on them, but only have about 300 miles on them thus far. I think it mostly depends on what rpm range you plan on hitting. if you're rarely going to go over 4k and wont go over 6k then 918s should be good, if you're planning on hitting 7k, or you are regularly going up to 5-6k then just spend the extra on a good set of duals. a broken $20 spring can cost alot when your piston gets introduced to your valve.

    Why push the limits of something? Makes it sound like you want it to FAIL!!!

    We've been using the Lunati Dual Gold springs, very competitively priced. Comes complete with seals and all the other stuff.
    They are quiet and support up to a .660" lift.

    I agree, dual springs are a good investment. And the little bit of extra seat pressure is nice if you ever decide to go FI.
