    You have several choices, complete Riva valve train upgrade which replaces your stock springs, comes with titanium retainers and rocker shaft bolts of which you will need to replace

    Or, you can install the Les Cooke alloy retainers. These retainers are designed to put more tension on your stock springs to give your engine the capability of handling more RPM's. You will need to buy rocker shaft bolts separately

    Riva also has a retainer kit that's much like the Les Cooke retainers in that they also put more tension on the stock springs, but they are titanium. This kit comes with the needed rocker shaft bolts. (these retainers are not the same retainers that come with the complete Riva valve train upgrade)

    FYI, the Riva ECU has an 8650 RPM rev limiter. You will want to pitch your impeller to run between 8500 and 8600 RPM's
