Everything you said makes sense. What are the guides made from? Also, where were they made? I have to say one thing about valve guide seals, usually you will get the most smoke from them after the engine sits for a few hours. Also, you will most likely see the most smoke from them when under heavy acceleration. Is that what you are experiencing? Also, the brand you mentioned, I never heard of. They need to fit tight on the valve guide. Otherwise, they will leak. As far as the machining marks, that is normal if they were redone, but were they properly checked to make sure they are within specifications?
