ABH_ Animal 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.

In Stock_ Currently Available with >1 Week Lead Time

  • Fully CNC machined from a solid billet of aluminum
  • Made in the USA
  • 4 bolt flanges with silicone O-ring seals (no gaskets to worry about) superior seal
  • Offset intake valve to deshroud from cylinder wall (better flow)
  • Offset Rocker Billet Roller Rockers (to accommodate the offset valve location)
  • Shaft rockers are lighter than stud mounted and at least as rigid
  • The correct intake to exhaust valve size, smaller exhaust valves allows us to move the intake valve away from the cylinder wall
  • High velocity, correctly sized ports, peak power ~8750rpm with a flat long power curve on typical build.
  • Rockers made from 2024 material for its superior mechanical properties 
  • Rockers use  full compliment needle bearing pivot for minimal friction
  • Non Beryllium Copper Valve Seats (4 times the heat conduction of steel seats to remove heat from valves) (same material as cup car engines)
  • Premium Stainless Valves 1.35" Intake and 1.1" Exhaust
  • High Efficiency Combustion Chamber with 10mm spark plug to reduce distortion
  • Maximized cooling by use of many well placed fins to aid in reliability and power
  • High performance  manganese bronze valve guides
  • Competition Cams premium valves springs Included_Constructed from Pacaloy®
  • DED Billet 7075 light weight high strength retainers

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. With critical items included it is designed to be a  true bolt on product 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).

      • .315 or less lift Cam Shaft_with the 1.25" rockers this lift is optimal.-Bigger Cams waste torque and reduce the overall power output of the head.
      • 28mm to 32mm Carburetor, or HL 380 series Tillotson style carb_  Intake ID is 1.25"
      • Methanol Fuel is highly recommended for its cooling and power effect.
      • Race Gas/Premium Mix_ 50/50% but, a 206 could probably run on 93 oct OK for drag racing applications where less heat is present.
      • Timing 28-31 on Gas  31-34 on Methanol

       Requires the use of a SFI approve Billet Flywheel!  Never use anything but an SFI billet flywheel with our engine products.

       This head is designed for sanction racing events only and must be installed by a qualified technician with knowledge of the sport you compete in. 





      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.
