Valves have seals instead of gaskets and if one was bad you would have oil on the spark plug for that cylinder if you were to take it out and inspect it. A bad valve cover gasket would leak oil on the outside of the engine. a bad head gasket would put oil and/or pressure into the coolant system, coolant into the combustion chamber causing white smoke, or coolant into the oil.
signs of a blown head gasket can be:- coolant leaking outside of engine from head/block area,coolant in engine oil, oil in radiator,over heating of engine.loss of pwer.loss of coolant from coolant resevoir, smell of coolant while driving, and not being able to tell where it is coming from

These are signs, not guarantees that it is blown. Oil and/or metal pieces under the engine area. Still a sign, but a more serious indication.
