    2007 RXT Valves & Valve Springs Question

    I have a 2007 RXT with a little over 100 hours. It has 42lb injectors, 255 charger, intake, exhaust, and all the other supporting mods with stock tuning and stock internal intercooler but plan to change some day. I run it pretty hard and WOT a good bit. I hear a lot about dropping valves on these skis and was wondering with my set up is there any need to do something like the Supertech Dual Valve Springs Titanium Retainer Kit and/or there lightned valvesprings?

    The valve dropping issue was prior to 07. You have to raise the factory rev limiter to start worrying about valvetrain upgrades on the 07
