The only way to know for sure, is to remove the head and have it magnafluxed. If it has either of the above in the question, the head would have to be removed anyway.

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.

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.

Have a compression test run to see if you have a problem with the head or gasket. Once you find out you do, then you must remove the heads in order to determine what the problem is.
