I have over 300k on my original head gasket. I'm sure there are other factors that causes head gasket failures in these engines such as the EGR system. I took my EGR off a long time ago.
Another thing I've noticed in my years own an 80 is that there is some type of solid grey matter builds within the cooling system. When I replaced my radiator, the old one was about 10 lbs heavier full of the grey stuff. Now I have a coolant system filter installed. I also flush the system every year.
