Low cost way to add performance. All heads are 4 bolt Valve cover, unless specified. Race Head, Chinese OHV Casting, 14cc or 22cc depending on desired compression:
  • Fully Ported and Bead blasted
  • Milled to increase compression
  • Lightweight Stainless Valves

18cc 32/27mm 5mm Tillotson Big Valve Head CNC ported 18cc 32/27mm 5mm Tillotson Big Valve Head CNC ported

CNC Ported 18cc 32/27mm 5mm Tillotson Big Valve Head CNC ported
The Head comes with 32mm intake and 27mm exhaust valves: 5mm stems. Precision multi-angle job, Valve Bowl Area, Cleaned up to match the seats. the valve work is performed on Rotter Seat & guide machine accuracy and precision. Heads are vacuum checked after the valves are installed to ensure your air-fuel mixture and combustion happens in the cylinder. the heads milled to ~18cc combustion chamber. the cylinder head is CNC ported on our state of the art multi-axis HAAS machines. CNC ported rather than hand porting makes each port job consistent and accurate from head to head. This also reduces the cost of labor to make it more budget-friendly. Springs, retainers, rockers, gaskets, seals, or valve cover are omitted.
Head Specs:
  • Intake: 32mm,5mm
  • Exhaust: 27mm, 5mm
  • Combustion Chamber: 18cc, Non-Hemi

EC Evolution Performance Cast Cylinder Head EC Evolution Performance Cast Cylinder Head

The EC Evolution Performance cast Cylinder Head isn't just changing the game: it's rewriting the rules.

The EC Evo Head is a big valve non-Hemi Head with 33mm intake and 27mm exhaust with 5mm stems for the Honda GX 200 and many clones, including the Predator 212, Tillotson 196-212-225, wild cat 223, and Duncar Engines.

When EC Designed the Tillotson Blocks, The Goal was to increase the performance and durability of modified engines while lowering the build cost. The EC 236cc Engine kit was a manifestation of that goal, but it still lacked one area that was still lacked one area that was still relatively expensive. For racers to compete in 14.5ci open engine kart classes, billet heads were considered the best offered, whether it was stock or modified.

The Evo was to answer the cost of those cylinder heads, but it wasn't the only goal. The Evo allows you to use the same intake manifold, exhaust header, rocker arms, valve cover, valve springs, and retainers currently on the market for Honda, Predator, Tillotson, or Clone non-Hemi Heads. So not only are you not replacing those parts, but you now have more options for those components. Most billet heads offer only one ratio, which may limit your cam or spring choices.

There are also situations "Billet" heads are not permitted, and within minibike drag racing, there are "cast only" racing and records. These classes will often allow extensive modifications to those heads rather then allow billets. As we said, the EVO is here to rewrite the rules and change the game. The EVO is a cast head the rivals the performance of a billet head.

Big Valve SBH Billet Head GX and Clone Stage 2 Full Kit Big Valve SBH Billet Head GX and Clone Stage 2 Full Kit

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).

  • 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.
  • 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
