I'd like to know too. There are some awesome small waters with big carp that I've fished but unfortunately they're infested with bullhead too. Secret Swim comes to mind...
I even caught a few bullhead at Reading the last time I was there, which was discouraging as I had never gotten one there before.
Someone told me once that the only cure for bullhead infestation is a big flathead or three.
