Head, Racing, GX160/GX200, 22cc : Aftermarket (Chinese) Core

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
  • Aluminum retainers and Split Keepers with stainless valves.
  • 3 angle valve job
  • Lash Caps
  • Choice of single or dual springs

Heads are typically built to order, Allow 1 to 3 days to ship

WARNING: 32/28 valves are subject to seat failure. They should only be used in methanol applications. And to be honest, the 28/25 make as much, if not more power (Velocity is much better)

Hemi heads are subject to coil bind using .070" Valves
We do not recommend 1.3 rockers due to valve to piston clearance issues.
