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)
