cask beers do they need a head

The brewery I go to in Bend oregon uses a small disperser on the end of the cask beer pump to add more air and a bigger head is this necessary or just a gimmic it does change the taste of the beer over when the disperser off.

 

Thanks bob brubaker

    It is a “sparkler”
    It’s personal choice. If you served it flat in the North you would be told to take it away. If you served it with head in the South you would be asked to fill it up.
