I HOPE the new cam changes that.   My KH tapers off at around 5k
and Really tapers at 5,500.  I'm hoping a quick change to the MC
will help it go to 5500 but if your results are good I may just
wait and then go to what you did.
  But I need the low end torque so I'll have to customize a bit
from what you did. I want it to breath better but dont want to
lose much down low.
