I have a 02 Heritage Softail with SE AirCleaner and Python II slip ons. Should I be running with anit reversion cones?

Simple answer. No, Not Needed, Nope....

AR cones are a stop gap measure used when reversion is playing a big factor with your power.
Drag pipes are a prime example of when AR cones are used.
