Anyone racing in a Heads up class, Super Stock, or Comp Eliminator, will say yes. They have to to stay competitive. Anyone else, probably not.

There have been more limited run, high end cast single 4 barrel intakes pop up from guys like Chris Uratchko. They are a $1500 cast intake, but their selling point is they don't need all the port work to perform. Brett Miller's W8 cast intake would fall under that also.
