    maximum lift for valve springs

    Anybody know the clearance you are supposed to have for valve springs. For example I will be installing a cam with .563 lift how large of a lift should my spring accommodate. (I saw some springs for sale that allowed for .580 lift)

    Those springs will work.

    I personally would only run Comp 918 for single springs. I'm a picky bastard when it comes to certain components.
