As others have said, if you just want a will-fit replacement, anything up to the 130/230 will do. If you want identical, you need to look for the A/B/BN engine.

The changes I can think of at the moment (working off the (6342) A/B baseline) are:

-all the crankshafts (in this range) should interchange;
-any block after the A/B will have the front bolster bolt by the hydraulic pump threaded in the block expecting the bolt to come through from the bolster side (opposite of A/B);
-early Super A/C (251069) sleeves should interchange with yours;
-late Super A/Super C/100/200 (354898) sleeves will not interchange;
-130/230 (366204) sleeves should interchange with yours. (I should say aftermarket sleeve&piston sets here; there has been concern posted on whether the factory ones are interchangeable and I haven't taken the time to get to the bottom of that yet.)

The casting numbers (in parhentheses, and located behind the oil filters) should be used rather than the tractor the engine is on at the moment, and as Hugh mentioned, be aware some of the blocks have been modified internally. Ref this thread for some more info:
