Exhaust flange nuts

I had my exhaust manifold replaced last fall. After a short time the exhaust flange nuts came loose. I went to a muffler shop and after getting a better gasket from Olson’s they were able to get it tight.

Now it has loosened again after a few short drives.
It makes the engine very noisy.

They’re there a special washer to help this.?

I understand that Loctite won’t work because of the extreme heat.
