The key to head gasket longevity is, as you've surmised, never overheat the engine.
About 6 months ago I had a thermostat stick closed on the highway, causing the temp gauge to make a mad rush for the 'red zone'. I immediately shut the car off and called a tow truck. Now, 10,000 miles later, it seems the headgasket survived.
I do have a theory, though, that any gasket between dissimilar metals will eventually fail, given enough thermal cycles. I have a Ford F250 4x4, about 12 years old now. Perfect shape, really low mileage, never abused. Every aluminum-steel gasket, front cover, intake manifold, etc. failed within a few months of each other. Failed good too: Bars leak had no affect.
There are guys on this board that have over 250,000 on the original headgasket, but there is really no way to know how many thermal cycles the motor went through.
My 9000 goes through an average 2 thermal cycles per day: 35 miles to work and 35 miles home. The 'wife car' might go through 20 thermal cycles in a 20 mile day. The 'wife car' also went through 3 automatic transmissions & 1 one motor (balance shaft problem) in the first 100,000 miles despite imm pecable maintenance and a driving style such that she's never gotten a ticket in her whole life.
