Athena, Evo cylinder head and base gasket kit. 3-5/8"

Large 3-5/8" bore. Kit for servicing one engine.
Includes PTFE coated blue head gaskets and fibre reinforced paper 'type A' base gaskets.
Includes oil return O-rings.
Explanation of 'type A' (early style) and 'type B' (late style) gaskets: There are 2 types of cylinder base gaskets available for Evolution models. For convenience, we will call them 'type A' (early) and 'type B' (late). The 'type A' gasket was introduced on the 1984 Evolution Big Twin models, and can be used on all 84-99 Evo 1340cc models, fitting the cylinder base contours perfectly. They fit 86-22 Evo XLs, but protrude at the cylinder base. This can be an issue with silicone-beaded base gaskets. The 'type B' gasket was introduced on the Evolution XL Sportster models in 1986, and fits all Evo XL models, as well as all 84-99 Evo 1340cc models, although the Big Twin cylinder base is slightly larger than the gasket. The 'type B' is the only gasket type 'The Factory' supplied from 1986 onwards for both Evo Big Twin and Evo XL Sportster models. Both 'type A' and 'type B' gaskets have an identical inner diameter, oil hole and bolt location. The gaskets for the front and rear cylinder are identical. The only difference between the 'A' and 'B' gaskets is the outer perimeter.
