    Highest Intake Port Location in the Industry
    DR 1213 - 12.5° Intake & 13.5° Exhaust Valve Angles
    GB 2000 - 13.5° Intake & Exhaust Valve Angles

    The Brodix GB Series is in a class by itself. These 13.5° valve angle heads were designed with sprint cars, late models, and drag racing in mind. The GB 2000 series features improved spark plug angles, highly efficient combustion chambers, raised intake ports, moved valve centerlines, and a raised valve cover rail. The latest evolution of the GB head is the DR 1213 which features a 13.5° exhaust valve angle and a 12.5° intake valve angle for even greater air flow. Special components required for the GB 2000 series and DR heads are injectors or modified intake manifold, sheet metal valve covers, and a shaft rocker system. 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. The industry standard has been taken to the next level with modernized CNC porting. 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 interlocking valve seats installed. Bare heads sold in pairs, Assembled heads sold individually. !
