Repairing a blown head gasket can be expensive.

But let's try to figure out what is going on.

If the head gasket is really bad, (as compared to a small leak) the pressures in the combustion chamber will immediately start to over pressurize the coolant system.

If it's happening because it's over heating, (say because the thermostat isn't opening) it would take a few minutes

and you can't completely trust your temp gauge or warning light when it comes to a situation like this.
If there is air in the system (or steam ) the temp sensor isn't effected much because air and steam don't transfer heat as well as water does.

It's a small world.
I'm in Kansas City MO.

The shop may not be wrong about the intake manifold leaking.
The 60degree V6 Chevy engine, (2.8, 3.1, and 3.4) are known for having a problem with the intake gasket.
GM has come out with an updated gasket kit to help solve the issue.

But normally the leaking gasket would not cause the problems you are having

I cant speculate if it will work or not.

While I do think JB Weld is an excellent product, it is not a magical potion that can fix everything.

Good luck

I would have to see how it is broken.
If the threads are just stripped out, a heli-coil would most likely work.

If part of the casting broke away because the bolt was hydrolocking in the hole with gasket maker in it. That's something that would just have to be looked at in person.

And you can ask as many questions as you want.

Thank you for the kind words,

that's not a good thing.

It may be possible for the hole to be drilled deeper.
Then threads cut in the hole with a tap.
And a longer bolt be used in it's place.

But someone with experience should probably look at it to determine if that is possible

It depends on how bad the leak is.

Worst case, is it would leak water into the engine oil and the bearings would be destroyed pretty quickly.
You probably wouldn't still be driving it if that was the case.

Most commonly, a little bit of water is sucked into an intake runner and is vaporized and sent out the exhaust.
You would probably be noticing white smoke.

Either one could cause the engine to over heat

Does the oil looks like a chocolate milk shake?

If yes, then you need to stop driving the car until the intake gasket is fixed.

Then change the oil a couple of times in a row to get the water out.

And hope no engine damage has already happened.
