My first post as well. I've just purchased a 98 GT , 106k, with head gaskets just done. A friend from work has a 97 Outback - started over heating this week. I used to work on Saabs and for a while Saab had mucho head gasket problems. One fix that really worked was annual retorquing cylinder head bolts to factory specs. No small task, on my 2.5, from what I can see. But the engine design and mix of materials subjected to thermocycling several times a day requires regular retorquing to maintain the clamping force that holds it all together.
