I like what you did with your valve covers and I would have done the same or powder-coated them if I was going for that kind of look. Since I have the Corvette coil covers I don't need to make mine fancy though.
I wish you were close to me as I need some custom work done to repair my coffee table top after my pup chewed on it. I do some wood work and refinishing but I don't have the stuff to build a whole new tabletop.
