Includes two of each in thicknesses of .005", .010", .015" and .020".
These are special copper base gaskets for mechanics who want to achieve a specific compression ratio.
Explanation of the type A gasket: The 'type A' gasket is the early type introduced on the 1984 Evolution Big Twin models, and can be used on all 84-99 Evo Big Twin models, perfectly following the contours of the cylinder base. They will fit 86-22 Evo XL models, but will protrude at the cylinder base.
