Gaskets and bearings are the same. Rings are larger for the 250 so they don't work. I assume someone has given you a complete o/h kit for a 250 so thats why you're asking? One area to be careful of is with the cam bearings. Up to 1970 the 2 bearings at the ends of the block have a different OUTSIDE diameter than the 2 center cam bearings. The 4 bearings inside diameters are all the same for the cam journals. If you or your machinist is getting these bearings separate from a complete o/h kit for a 194 then be sure to check this carefully.
