Thank you. It is possible it is a hose on top of the fuel injection or the head bolts were not torqued right. Checking one of the valve taps, and the muffler may also be falling apart.

I'd touch the radiator after it's warmed up and see if it's still cold if so replace the radiator with a New One

Are your radiator fans working? They should come on automatically when the a/c is on, if not, the temperature sending unit and/or fan relay are suspect.

I have an old 03 Buick lasabre and had the head gaskets replaced, replaced a lower intake and replace the upper and take. New radiator also and it's still saying it's running hot
