10134359
18° Aluminum Cylinder Head

  • Low-port 18° aluminum cylinder head for maximum-effort competition engines
  • Offers significant improvements over conventional head designs with 18° valve angles (vs. older 23° angles) and 43cc combustion chambers
  • Spark plug holes are centrally located and valve centerlines are relocated
  • Exhaust ports are high-flow
  • Head face has an extra 0.080" of material for 9.1:1 compression, and up to 2.200" intake valves can be used
  • Shallow wedge-shaped combustion chambers allow builders to achieve high compression ratios with small piston domes
  • Heads do not include valve seats or guides
  • Aftermarket shaft-mounted rocker arm assemblies and pushrods are required
  • Piston domes and valve pockets must be matched to the revised combustion chamber design
