In either case, the head has to be removed. Once it's off, a machine shop can "Flux" the head. IF IT'S and iron head, they put a powerful magnet on the head then spray powdered iron to see where it lines up. If the powdered iron gathers along a line, you have a cracked head and it isn't worth anything more than scrap prices.

What is the difference between a cracked block and a blown head gasket?
A cracked block means that the engine itself is cracked. A blown head-gasket means that the gasket between the engine and the head has blown. Either can be caused by overheating the engine. When an engine overheats the head can warp causing the head-gasket to give out. In some engines the heat cracks the block. If the block is cracked, it's over. If the head-gasket is blown you can always machine the head surface and put it all back together.

How do you repair a blown head gasket or cracked head?
A blown gasket can be repaired by replacing the gasket...if you are talking about the head gasket, then you have to remove the cylinder head from the engine block and replace the gasket that is inbetween them. Cracked heads generally have to be replaced because they are made of aluminum which cannot be repaired permanently once it is cracked.
How can you tell the difference between a blown head gasket cracked head or cracked block?
If you suspect the head and/or the block, have them "magnafuxed" by a machine shop. On the other hand, as you're pulling it apart, check the head gasket and if it's shot, there is usually only the one problem.
