  • Some pistons are listed with a range of compression ratio's. The low number is determined with an un-cut deck and the higher number is determined with .030 piston to cylinder head clearance.
  • Always check piston to valve clearance - If using VTEC or like mechanisms-check with longer duration higher lift lobe.
  • Always run at least .030 piston to head clearance including gasket thickness.
  • If piston appears to be different than expected, please do not hesitate to call Wiseco at 800-321-1364 to verify compatibility
