GSC Recommendations:
  • Check Pictures for cam placement. Long nose = Left Side, short nose = Right Side
  • Due to the lobe size, head castings may need to be filed down slightly for clearance - Please check during install
  • Proper break-in and running high zinc oil is a must on flat tappet engines
  • Must be installed by an experienced technician
