RFD 2300 Series 13.5*

We have several ports for this head, for Comp Eliminator, Sprint Car & large cubic inch.
This is one we are very proud of. The flow numbers are incredible for a wedge head, but the port isn't big, slow or lazy. The opposite is true. This head has very good airspeed and is far from lazy and will recover well off the shift.
We have several versions of this head available with ports designed for circle track, dirt late model, sprint car, road racing and drag racing.

We have several versions of this head designed for Dirt late models, sprint car & Drag etc. !
