The only cracks that you need to worry about on these heads are cracks in the valve area. It IS normal for them to crack around the energy cell (the combustion chamber area). These cracks will not hurt anything, cause a loss in compression (unless you have one from an energy cell to a valve seat). The Gassers were not hard on heads. They had a different head than the diesel in order to lower the compression. Without the compression and the precombustion chamber, the heads did not have nearly the stress the diesels had on them. Many will say that the 262 gas is one of the best gas tractor engines out there. Compare it to a 4010 gas and it just sips fuel. Another thing you need to watch for with a head is a warped head. This will happen from overheating and not properly cooling it down after overheating. Warped heads normally do not come from just not cooling it down after a hard days work, that seems to be where cracks come from. If you are really looking seriously into a diesel, and this is a concern, let the buyer know and ask him if he will do a compression test for you. This will reveal almost any flaw that the head could have at the time. If the head is in good shape when you buy it and you take good care of the tractor and operate it correctly, the diesel should not have any head problems. The gas doesn't need nearly the attention. I have never heard of a blown head gasket on a normal gas engine (pullers with compression close to a diesel don't count :) ). There is not a head I know of for a diesel that will not develop cracks around the combustion chamber. There are still some good shops out there that, in case something bad does happen, could magnaflux and weld up a cracked head to near new. A lot of machine shops who have never seen a buda head may think you have a bad head with the cracks around the combustion chamber, but really they are just normal for the head. Also, there are remanufactured heads still avalible. Check out the allischalmer(dot)com forum. There are quite a few people who have experience with 262 diesel budas.
