I over heated my car and blew gaskets and crack some heads. They were all inspected and fixed. But now when it idles the temp gauge goes up and the air from the vents get cooler. Once you drive it and stay about 1500 RPM the gauge will go back down. When the gauge is at half way the fan comes on and works fine. I can find no leakages. All New: water pump, thermostat, temp sensor, and radiator cap.

Overheating that severe could have done a lot more damage that you realized. The block could be cracked, damaged or warped. An overheating that severe is usually not a good idea to try to repair. It sounds like you are still getting combustion gases into the cooling system.

When we were changing the heads and gaskets we had a mechanic come out and look over the block. He said he could not see anything significantly wrong with the block. When we run it the hoses to the radiator that water runs through are easily squished and don't harden or get tougher to squeeze. It holds coolant just fine.

No mechanic can tell you if the block deck is warped or the cylinder is round with his bare eyes and if he tells you he can, he isn't much of a mechanic.

Regardless of what you may have been told, if you are losing coolant without external leaks and you are losing the heater because of air pockets being formed, you likely still have engine damage and combustion gasses getting into the cooling system. The only real accurate way to determine that is using an exhaust gas analyzer to sniff fumes at the radiator filler to measure hydrocarbons in the coolant. Those blue water chemical tests are rarely good at picking up small to medium leaks.
