hedman "tight tube" hedders?

Forgive me in advance, the pictures shown are from the "Forced Induction" forum here and are of Mad Dart's car (which is gonna be SICK!!!)... My disclaimer! these pics are of another members car and I hope I don't get yelled at for using them in another forum, if so I promise I'll do 3 Hail Mary's and go to bed without Ice Cream!
