Enginetech CHS1061L Left Cylinder Head Spacer Shim Ford 5.4L Engine

The Enginetech CHS1061L is a left-side cylinder head spacer shim engineered for Ford 5.4L engines where the cylinder head or block deck surface has been resurfaced below the factory minimum thickness specification. This shim restores critical engine geometry that is lost during resurfacing, bringing the engine back to OE standards.

Key Features:

• Manufactured from 0.020" cold rolled steel for consistent thickness and durability
• Restores valve train geometry and proper valve clearance after head resurfacing
• Returns compression ratio to OE factory specifications, preventing compression ratio creep
• Corrects cam timing that is affected when deck surfaces are milled below limits
• Eliminates timing chain flutter caused by altered geometry
• Left-side application — designed specifically for the driver-side cylinder head on the Ford 5.4L V8

Installation Note: This shim must be installed on the block side, with the cylinder head gasket placed on top of the shim. A sealer should be applied between the shim and the block surface. Compatible with conventional head gaskets only — not for use with MLS (multi-layer steel) gaskets.

The Enginetech CHS1061L is an essential component for any engine rebuild involving a resurfaced cylinder head or block on the Ford 5.4L platform, ensuring your rebuild meets factory tolerances and performs reliably long-term.
