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!

Since they must be replaced you might as well gain some power and mileage. Check out these features below: * Cast in high-strength and corrosion-resistant CF8 (304) stainless steel * Extra thick flanges have higher resistance to warpage and cracking * Individual runner into collector design with over 60 percent more internal volume * Port matched outlet with integrated gasket anti-extrusion ring provides 37 percent increase in outlet flow area * Additional bolt hole provides three studs for each exhaust port * Direct bolt on with no additional modifications or parts required
