"1 set of valve cover gaskets ($400)"

Gawd Allmighty is that a typo? I just bought '91 2.6L 4wd Trooper and I am doing the head gasket (hopefully just that but I haven't got in there yet). It sounds like there are a lot of problems with the heads on these things. I am seeing that using higher quality gaskets may help, but this figure is near what I paid for the car and thats just the valve cover? I dont want to do it twice thats for sure. As a former '91 driver do you have any thoughts on this? I like the old Trooper for snow camping trips as its
A)a big boxy dwelling for gear or sleeping and a fairly small engine for economy.
B) 4WD for the snow. But if this head issue is going to rare up again I dunno.

Is the head problem insurmountable?
