90 beretta overheating and no heat

1990 beretta 3.1
Ok, The car overheated, no heat blowing from heater. So I replaced the thremostat. Problem fixed for about 2 days. Then the same crap, car overheated with no heat. So I thought that it was a 1:1,000,000 chance that I got a bad one, so I bought another one. Still overheating, with no heat. So I took the thermostat out, and put a peice of cardboard infront of the radiator. Problem fixed again, car ran at normal temp., in town, little cool on highway. I also had heat. Then after about 2-3 weeks of running fine, it over heated again with no heat. I checked ALL hoses to see if one was kinked or slightly kinked. Water pump is fine. Gaskets are fine. Also, I did flush the the system in the summer, months before the problems.

Maybe one of your radiator hoses have separated on the inside which would restrict flow and cause overheating. Antifreeze?

Do the electric fans ever come on?

Have the coolant checked for the presence of hydrocarbons by a shop with a gas analyzer. If positive, blown head gasket.

Thats what it is, a bad head gasket. I've got it all apart now. Any tips before I start putting it back together?? I did check the head with a machined straight edge, and the head is not warped.

Have the heads checked professionally by a machine shop for straightness, integrity and bad valves. Specialized equipment is needed to do this. A machined straight edge won't tell you much.
