Engine Overheating Due to Leaking Headgasket on Cadillac Eldorado

Problem Description and Possible Solution

Overheating of the engine may cause the cylinder head to expand, severely straining the head bolts and damaging the threads in the engine block. This commonly results in a blown head gasket. Our technicians tell us the engine block threads must be repaired before the cylinder head is reinstalled.

Was told that the head gasket may be bad but I`m sure I checked the oil and there is no water mixed with it. motor does over heat and water will over flow. I also do not see any steam coming from the exhaust.,
Car keeps over heating, bought new radiator and thermostat but still continues to over heat, should i remove the thermostat and run it like that?
Overheating due to gasket and or bolt length to shallow. Hope Cadillac stands up and fixes the problem. After all the error is all there's.
Never repaired did not what to rebuilt engine, GM screwed us all with the 4.6 Northstar engine! Used Blue Devil GM made head gasket repair and dumped for 2500. The car was beautiful. I miss it. Also ha a 2000 Deville 120,000 miles on it same problem Blue Devil did not fix!
