International Harvester AA110?

At some stage in the AS models the "tilt valve "engines came out...........the whole head is different........I dont know if the bolt pattern is the same,but knowing IH ,it probably is.............I had a Gold 240 in my AB van,and I sold it pretty easy ,as I remember .........lot of years ago,tho...........I do know a lot of the 220s were wrecked trying to make them 240s,the rebore left the cylinders too thin..............However ,the 240 was just as thirsty as the 281.
