S410195006013/1U 3-5/8" big bore. Front & rear gasket set. Type 'A' gasket. .020" thick RCS (Rubber Coated Steel). Gasket with an embossed steel core with a .001" thick coating of heat resistant nitrile rubber on both sides. OEM replacement reference none. Note: Type A' gasket explained: Type A' was introduced on the 1984 Evolution Big Twin models, and can be used on all of the 84-99 1340cc Evo models and will follow the contours of the cylinder base perfectly. 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 & rear cylinder are identical. Only difference between the 'A' & 'B' gaskets is the outside perimeter.
