SBH GX/Clone Small Block Billet Head Stage 2
*Stage 2 kit adds- intake manifold, valve cover spacer/breather bypass or SVC billet valve cover, and pushrods in addition to the Stage 1 kit.
DED racing has taken its 20 years of air cooled cylinder head development experience and integrated it into our new billet Honda/Clone head. Introducing the SBH designed to be an affordable replacement/upgrade for the stock cast head. With its integrated rocker arms, superior flow and rigidity it offers performance and value that can't be matched by a cast head or even other billet heads. It is designed to be a true bolt on product where the critical items are included so you don't have to search far and wide to get your project together. This also allows us to ensure that things like rocker arm geometry is optimized and perfect. ( Simply, More Powerful- means we offer products that make your sport more fun not more frustrating).
