Timing Belt Truth

I have a 95 Subaru Legacy Outback. According to a website I was reading, non-interferance design engines can withstand a timing belt break without damage to the engine. If my engine is a 2.2 SOHC engine then it would qualify as a non-interferance type of engine, correct?

Therefore, my questions are:

1) Is this correct that my 95 Subaru Legacy/Outback wagon is a 2.2 SOHC engine (it has the original engine in it)?
2) Does an SOHC engine constitute as a non-interferance type engine?
3) If my belt breaks because of extended use and there is no engine damage would it simply require a new timing belt or additional work? If so what kind of costs would I be looking at?

1- yes it is.

2-SOHC stands for single over head cam
whereas
dohc is dual over head cam.
There is no bearing on whether it is interference or not due to the sohc or dohc.

3-I wouldn't expect more costs necessarily, but I would be concerned with it happening at a bad time.
AKA on the thruway, on the way home from happy hour, rushing your loved one into the hospital etc.,
There is the inconvenience, the tow bill, the diagnosis bill (hopefully there are accurate) and maybe at the expense of where you are and that shops schedule.

In 1995 Subaru went from roller hydrolic valvetrain to mechanicaly lash adjusted. Most people including techs from Subaru Get this wrong all the time. But If you have a 2.2l l from mid year 1995 to 1998 it is A interference engine. Do not find this out the hard way.I have seen more than I can count bend valves. Because there wasnt a engine size change when Subaru Changed the legacy platform in 1995 most pulications incorrectly report this as a non interference engine like the 90 to 94 2.2l were. But if you have ever done a t belt on one you will see that its possible to have the valves make contact with the piston. When turning the cam seperate from the crank shaft
