.020" Cylinder Head Spacer Shims

Cylinder Head Spacer Shims help restore the valve train geometry, valve clearance, compression ratio, and cam timing to factory specs on engines where the cylinder head and/or block surfaces have been resurfaced below factory limits. Precision cut from 0.020" cold rolled steel, each shim is produced using a CNC laser. This eliminates the rolled edge present on shims that are manufactured using a punch press.

Our shims are made from steel for several important reasons:

1. Steel has a higher heat tolerance than copper, the material used by other manufacturers. In hotter running late model engines, heat resistance is very important to insure the integrity of the shim. Steel is superior for this environment.
2. Steel cylinder head shims have a hardness factor similar to that of the block. This allows the gasket fire ring to properly "crush" as the head is torqued to spec.
3. Steel shims are less likely to be damaged in shipping and from mishandling or mishaps in the shop.

Note: .030" & .040" shims can be special ordered, call 1-800-521-2936 for details.
