I recently did an rebuild of my numbers matching 440 for my '69 GTX. (Details to come when I find time to do the write-up.) The original valve covers had markings on the front. I was told many years ago at a car show by someone who seemed to be in the know that these had to do with assembly identification at the factory. Does anyone have specific details or additional information about this? Now that I'm finished with the rebuild using the original valve covers and painted the engine the original Hemi orange, I'm considering duplicating the original markings. Any input will be appreciated. See attached pics.
