There are times when when it is necessary to put shims under the rocker pedestals to get the geometry just right. Surfacing the head or block, regrinding the camshaft or installing aftermarket rockers will all affect the relationship between the pushrod and rocker assembly. These .051" shims go underneath the rocker pedestals for small adjustments. Sold each. Ref: C-2A515, 2A515.
