Help convince me to go BB in my Duster?

This is probably the set I'll end up going with. It said they're rated up to 500hp, and that's all I'll need.
This is what I run with the 500HP, made my own exhaust to keep the heat away from the trans, added cut outs for down the track. I run the mopar ecu. I am still in the 11.50s with it.
