This head will help your big bore build reach its full potential! Optimized for bottom end pull and still able to hit high horsepower numbers on the larger displacement >224cc builds. Can easily flow enough for 3" bore motors yet with the offset valve centers it allows the 1.350 valve to clear a std 2.688" Animal bore.
This head has proven to be a winner for almost everyone we have sold. It has put racers up front all around the country. Proving to be a combination of the correctly sized components that even the most exotic builds can't compete with. Why? Because cylinder head development is so much more than the flow numbers that many sell off of. It is a balance between flow, port velocity, flow coefficients mach numbers, mixture motion, ect. When these values are not in check even the best flowing head will feel lazy and not be a winner, even if the flow numbers are said to be higher.
Our shorter valve design allows for a more stable valvetrain while maintaining port tumble. These engines like mixture motion because of the short intake manifold and not having a lot of time for fuel to atomize after the carb. Higher mixture motion port designs pull better off the bottom and just run better on the track. That is why very high port angles, though flow numbers may be better, just don't perform the same in all cases. They can have low mixture motion requiring more ignition advance and less than desired torque.

DED racing has taken its 20 years of air cooled cylinder head development experience and integrated it into our new billet Animal head. Designed to be an affordable upgrade from even the most exotic cast heads. 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 taking that burden off of the builder. ( Simply, More Powerful- means we offer products that make your sport more fun not more frustrating).
