Exhaust manifold leak

[JMBT]

The for the reply Starlight, do you think it would have distorted in 160k miles?? If it did distort, am I looking at another new manifold or just new gaskets, bolts, and retorque?? The upside, if there is one, Once I get the manifold off I will finally get to put an eye on the exhaust ports to determine if the valve guide seals a bad. Have been thinking that for awhile, but work has been fairly good so I haven’t came off the road to pull it all apart yet. Looks like the time is now! One more load to deliver than we will break her down.
