Head Gasket replacement question
 

Just real quick, blew the Head gasket on a 95 civ ex. Here's the catch. Car runs for 22 minutes before hitting a temp that opens the "Fracture" that causes it to over heat. Does that sound typical of a crack in the cylinder head or the block?? Am I being paranoid? When I blew a head gasket in the past, the car wouldn't go ten feet, much less 22 minutes. Seems off to me.
