Cylinder Head Spacer Shims

Cylinder Head Spacer Shims

Enginetech cylinder head spacer shims are made from .020” cold rolled steel that help restore valve train geometry, valve clearance, O.E. compression ratios and cam timing to factory specifications on engines where cylinder head and/or block surfaces have been resurfaced below factory limits. Cylinder head shims solve the common problems of lack of valve train geometry, compression ratio creep, and timing chain flutter. Shims should always be installed on the block side with the cylinder head gasket on top and should be used with conventional head gaskets only. Find everything you need all in one place.

  • Use on engines where extreme resurfacing of cylinder head and/or block head surface has occurred

  • Made from .020” cold rolled steel (thickness of steel shim may vary).
