It looks as if the install took a major turn for the worse. I asked a question online to gm techs about my problem.Just read here as follows:It speaks for itself my head gaskets were affected causing more damage.

Got the car back and engine immediately started running @190*F at idle and gauge rapidly moves to 210*F fahrenheit occurring immediately upon driving. The car finally cools down when the high fans both come on to cool it down to 190"F. The car never did this before and is running a 180*F thermostat and the computer is programmed accordingly to run that thermostat. Taking all that into account considering my car never ran hot or overheated while in my possession. Was it an installer issue or a mechanical/electric issue. The following have already been attempted:New 180*F thermostat,New coolant sensor,exchanged coolant(dex-cool) 50/50 mix,and vacuumed-bled/filled with Uview Airlift coolant tool.
If the cooling system was bled incorrectly by the installers of the lower intake gaskets wouldn't that cause the damage to the head gaskets. Also, I am not losing any coolant, if there was head gasket damage wouldn't I lose coolant or be burning white smoke from the tail pipe?

An air pocket in the cooling system can definitely cause overheating and damage to the head gaskets if the engine were run long enough in this condition. This is about the only thing that could be causing the overheating issue you are now experiencing.


Also, I am not losing any coolant, if there was head gasket damage wouldn't I lose coolant or be burning white smoke from the tail pipe? This would be my final answer needed to satisfy my question and curiousity in order to get my vehicle repaired.

You will not always pull coolant into the combustion chamber with a damaged head gasket. The combustion pressures are high enough however to push combustion gases into the cooling system.
