    50+ Horsepower Increase Over Stock
    Small Block Ford Heads!

    20° Intake & Exhaust Valve Angles

    The Brodix ST 5.0 Series cylinder head was developed to fit the Ford Windsor engine. Out of the box, completely assembled ST 5.0 series heads produce a 50 horsepower increase over other stock heads, and the combustion chambers may be milled into the mid-50cc range. All existing stock Ford 5.0L accessories (including the stock non-adjustable rocker arms which are required use on the ST 5.0 series) can be used in the installation of the Brodix ST 5.0 series. A modified version, the Brodix ST 5.0 R series, allows the use of 7/16'' Ford roller rockers. The exhaust ports are raised .500'' higher than stock Windsor heads on both versions. The BP ST 5.0 R series is completely CNC ported and outflows all other heads in its class. While creating the 100% CNC Ported BP ST 5.0 R series, the professionals at Brodix invested many long hours on the flow bench and at the track developing a completely ported cylinder head. The bottom line is that Brodix builds you the most accurate, best flowing out-of-the-box cylinder heads available at the best price. Every casting is poured from A-356 virgin aluminum and tested before Brodix utilizes their in-house processes such as finish machining and heat treating to assure that you receive the best products for your hard-earned money. Other features include a thick deck surface that is compatible with nitrous, drilled and tapped holes on the ends for standard drive accessories, phosphorous bronze valve guides and hardened valve seats installed for unleaded fuel. Sold in Pairs, 2/pkg. !
