it ran before you changed the head gasket right? make sure your timing belt is on without a skipped tooth... a skipped tooth will still run but not too good... two skipped teeth however probably won't run... if you did something with the distributor, that's what you should check... pull out the spark plug wires and try to start the engine... your wires should arc if you put it near ground somewhere, if it doesn't then there's your problem... check your fuel too... bad fuel? clogged injectors? forgot to reconnect the injectors? could be so many possibilities...
