The Enginetech Cylinder Head Spacer Shim helps restore the valve train geometry, valve clearance, compression ratio and cam timing to factory specifications on engines where cylinder head and/or block surfaces have been resurfaced below factory limits.  Use this shim with conventional head gaskets only.

  • Use on engines where extreme resurfacing or cylinder head and/or block head surface has occurred
  • Shims correct compression ratios and restore assembled heights to factory specs
  • Made from .020” cold rolled steel (thickness of steel shim may vary)
