When you took some fuel out of your load site for cruise did you not see a rise in egt?
Im only asking as i tried this on my brothers zvh and after about half an hour of doing about 60-70 mph we pulled over and found the manifold glowing and we were only in the 14s afr so we richened back up to low 13s and all was fine for the rest of the journey apart from it using loads of fuel.
