I don't know the answer offhand, but it is possible that Kohler could have machined a casting marked K301 to k241 spec's. You could measure the cylinder and that'll tell you. If it's under 3.375 inches, then it's a K241. If it's over 3.375, then it's been repowered, maybe with a short block.
And if I could get a good used engine for $100, I wouldn't hesitate to go that route.
