Yes, a head gasket can blow and cause the engine to overheat. Happens all the time. Yes spaying cold water on an engine that is at full operating temperature can possibly do some damage. Not likely, but possible. Spraying water on a warm or cold engine will do not damage to the engine. It may however damage parts such as the alternator, or some sensors. Never use a high pressure spray.
