Buc, looking thru my parts catalogs shows that the K-80 was the first year to use the sealing rings in the crankcase. The K-80 and KA-37 are the last years with the full opening for the carb. The later crankcase have a odd shape with a small hole for the idling intake. It appears it worked fine with the later ones for XR55. So any block from K-80 up would work. Hopefully you can get it going without swapping.
