    Top Selling, Bolt-On Performance Head!
    23° Intake & Exhaust Valve Angles

    The Brodix Race-Rite 23-degree Small Block Chevy Aluminum Cylinder Heads are designed by Brodix for maximum out-of-the-box horsepower. Every casting is poured from A-356 virgin aluminum and tested before Brodix utilizes their in-house processes such as 100% CNC machining and heat treating to assure that you receive the best products for your hard-earned money. Solid, phosphorous bronze guides are used to reduce valve leakage and oil consumption. The ductile iron valve seats are installed for use with unleaded fuel. Race-Rite heads are also milled and drilled on the ends for accessory mounts. The dual valve cover bolt pattern allows you to use either the traditional perimeter-style bolt pattern valve cover or the late-model center bolt pattern valve cover. Sold in Pairs. Made in the USA!
