I looked at the picture of the valves. There are others on here who may be able to offer a better guess but I'd say you may have a valve seal that's leaking. The valve on the right looks dry while the valve on the left appears to have a greasy buildup that, at least to my mind, is the telltale sign of an oil leak.
Sorry for the late response, I must have missed your post somehow. I agree with Tim as long as it is oil. If it is oil, I would not worry so much, as it will most likely be either the oil seal at the top of the valve guide, the valve guide being worn out or the valve itself. Almost everything possible will be rebuilt during your valve job.
If it turns out to not be oil but carbon buildup, the difference between these two particular valves may be fuel/air mixture problems, assuming you are running a dual plane intake manifold. One valve would be supplied by the upper plenum while the other is supplied by the lower plenum. Possibly one is getting far more fuel by the carburetor than the other. I do think it is most likely oil though.
I would not worry about destroying the exhaust manifold, it was already destroyed by the corrosion. Just glad the bolts came out of the head. Have you considered going to headers, or are you looking to do a complete factory restore?
Not much help here on the windshield frame. Mine did not need any attention because of preservation I did on mine 40 years ago during a windshield replacement. Tim has the most experience there.
Glad to see you are back though.
