Champion Ported Iron Heads
Product ID: HE103

Details 

Considering the purchase of a pair of ported Buick cast iron heads? If your not purchasing Champion CNC series, then you are not getting the most complete, consistent, and accurately machined Buick Iron Heads on the market today! The process begins by selecting only the best factory castings to assure the highest quality product possible. After cleaning and inspection the heat riser passage is filled with aluminum to enhance exhaust flow. The castings then begin the porting process on a CNC machining center. All operations performed on the CNC are completed in one setup eliminating the possible inaccuracy's that result from moving parts from one machine to another.
