Summit Racing™ precision cast cylinder heads are made from tough A-356 aluminum alloy and feature Permanent Mold "As-Cast" technology. Port accuracy is unrivaled--meaning CNC porting is not required to provide superior flow. The result is CNC-ported performance at a fraction of the price! We start with precision CNC-finished faces and bolt holes for accuracy and fitment. American craftsmen expertly size and install the manganese bronze valve guides and interlocking ductile iron seats before finishing with a competition-grade valve job. From there, the decks are given a final pass for superior finish. They are finish-assembled in the USA with top-quality components like PAC Racing springs, fasteners, one-piece 21 4N stainless valves, machined locks, Viton® seals and chromoly steel retainers. The final result is the performance you want and Summit Racing™ quality you TRUST!
