Since the Magnum engines really don't make any more power above 5000 rpm,
you don't have to worry about the 5500+ RPM Kit. (Why they state that is
beyond me for a stock engine.)
I recommended it since it's a matched valvetrain replacement and is very
stable for normal street driving...definitely better than the stock setup.
