Get a sniff test done to determine whether it's a head gasket. Is there any white smoke from the exhaust? Oil in the coolant? Mayo residue in oil cap? Does your heaters blow cold when set on warm? Does the bottom radiator hose feel squishy or cold when engine is on?These could indicate a head gasket but not guaranteed....as already mentioned best to get it checked out by an expert. It could be something simple like an airlock or the coolant cap seal has had it etc.

Header tank boiling noise may well be the air lock in the coolant.Does it sound like it is coming from behind the dash?
Imprezas are very hard to fill with coolant.See the many posts on here regarding the problem.

Could be a very small hole/split in on of the coolant pipes spraying coolant onto the hot exhaust when hot & under pressure.My legacy did the same & looked like Thomas the Tank Engine coming down the road.
