How would stiffer valve springs do for your redline? Would they bump it up a few hundred RPM? Perhaps lengthen the engine life for those of us who like to rack and roll near redline everywhere we go? Anything wrong with this idea? I assume that it would come at a minute fuel consumption increase, but not a noticible one. brooks ( hey, it's 1 in the morning, I don't have to think very hard! :)
