I knew there were a few exhaust manifold mounting studs missing, most likely with stripped threads on the aluminum head. I replaced all of the studs except one, and had to repair three holes with M10 x 1.25 heli-coils. With the new gaskets and a good mount, the exhaust manifold was no longer leaking at the head. Unfortunately, there was another leak at one of the air pipe flanges. In order to replace that gasket (which was new) or to add another for more thickness, we would have to remove the manifold again.

4 out of 7 studs = leak |

I brought the manifold to a local auto parts store with a machine shop, for resurfacing |

The center stud was a little questionable, so we added a jam nut for now |
