Actually, rich running is usually indicated by a fluffy black coating. Lean running would be the crap welded to it. Pictures 7-9 would be lean running; picture 2 is rich.
Yeah, short of having an air-fuel mixture meter on the car when you were driving it, about the only after-the-fact 'forensic' data is in the spark plugs. And if you were running rich AND lean, you'll probably have some mixed-up combination.
But again, what to do about it? With the vacuum hoses all messed up, mixture was an iffy thing at best. Short of pulling the head to see if you've got any burned valves, I'd live with it. If the engine is running well now, enjoy it.
