Pressure in Coolant system with blown HG

I've seen alot of reference to finding pressure in the coolant system long after the car has been turned off and that this is one symptom of a blown head gasket. I've also seen that the tell-tale sign is a release of pressure from the reseviour tank long after the car has been shut off. How much pressure are we talking about here? What does it sound like. The reason I ask is that I hear a very slight gurgle noise when taking my tank cap off after the car has cooled overnight. I unscrew the cap very slowly, and for about half a second there is a gurgle and a hiss. If I were to try to quantify it, it seems like 1 or 2 PSI releasing, but definately not 10 or 15 PSI. There are no bubbles and the cyclinders look dry when I take the plugs out. Is this normal?
