They will fit 86-22 Evo XL, but stick out at the cylinder base. This can be a problem with silicone beaded base gaskets. Both type 'A' and type 'B' have identical inner bore diameter, oil hole and stud hole locations. Gaskets for front \u0026amp; rear cylinder are identical. Only difference between the 'A' \u0026amp; 'B' gaskets is the outside perimeter.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctr\u003e\n\u003cth\u003eUnit\u003c\/th\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/table\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cp\u003e84-99 Evo Big Twin; 86-22 XL Sportster.
