Answer A cracked head means the head itself has a crack in it. Usually between the valves. A blown head gasket means that the gasket that sits between the cylinder head & the engine block has a crach in it allowing the oil and water to mix.sually, when a head gasket goes bad, it is caused by a warped head. Heads warp when the engine overheats. In an extreme case, when an engine overheats the head and/or engine block can crack. But in any case, all are caused by an overheated engine.
