Sorry!

So here it goes: 2000 V6 3.4L, unsure of miles on engine as it has been replaced and we bought car from sister-in-law. Ran fine for months. Took it on a weekend trip 4 hours one way, total 8 hours. Come Monday son took it to school and about 7 miles in he called me and said car over heated. He pulled over and shut it off. It was a cool and rainy day. I take some water with me and reservoir is low or empty cant remember, anyway fill it up and proceed to take it home. Notice no defrost heat at all and temp. gauge starts to go up and up, luckily I'm at the top of a hill and shut it off and coast down and able to cool motor off and make it home without overheating.

My fixes: Water pump, 2 thermostats, newreservoir and cap, new radiator, new upper and lower hoses, flush of the system(before new radiator).
Compression test: 1) 155 3) 155 5) 145
2) 155 4)155 6)145
Noticed no water shooting out of spark plug holes when cranking motor
Oil looks good, no white smoke when driving. It will not get hot idling in the driveway and needle sits a little below halfway and heat will work after I bleed the air out of the system(steady stream of coolant from bleeder valve, no air). Now when I go and drive around town within a minute the heat is gone from the heater and if I were to go on the highway then the motor temp. will climb.

A couple of weeks ago I took out the thermostat and drove it in town for a while. Never got hot and didn't get to the half way mark. When it was time to go home went on the highway and drove about 5-7 miles and the temp started shooting up, so I immediately pulled over and didn't shut it off and the red light and chime didn't come on open the hood and the tank is spitting out water through the over flow tube, it cools down a bit and proceed home via down hills and shutting it off and coasting to cool it. So that's where I'm at. Should I go ahead and tear it apart to the head gaskets and replace or is there something else I'm missing that I can try.

Oh I did attempt to do the block test with the engine block test kit, but when the engine was at temp and I would proceed to press and release the bulb the hot steam was starting to warp the hard plastic tube that solution sits in. So I stopped.
