One of the most powerful heads for single carb applications, we've been building SB2.2's for many years. A great head for many forms of racing, including: Comp Elim, Fast Bracket, Boat, Truck Pull, Road Race, GT1 and of course, Circle Track.

We have a wide variety of port designs for the SB2.2, something for just about every application you can think of. What we don't have we can combine parts of CnC programs to produce a custom head for your application.

Recent tests show the RFD SB2.2 drag head to be the most powerful drag race SB2.2 available!
