I have a 1990 3.8na, and I'm getting really weird things with it. Some days the temp gauge will almost overheat, then fluctuate. I have heat randomly, the blower work and so do my flaps. It does tend to smoke IMO alot more then it should. I have no idea of mileage, odometer stop at 126k. I have replaced thermostat and bleed the system. When i go to take the radiator cap off, its got pressure behind it

I'd bleed any air out of the system first, but otherwise it sounds like signs that the head gaskets might be on their way out.
