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. Call one of our technicians to
