Used Pair of Mopar Performance P4529004 Factory Chrome Valve Covers B/RB 383 400 440. These are the good ones that have the Breather, PCV and oil cap in the same place like factory with baffles. These are the taller version. They have been discontinued for many years. These look nice, but not perfect, chrome has imperfections,small rust spots, dings, scratches, from use. Please look at all my photos, as they are part of my description. I will take the time needed to package these good for you, so they will arrive in the same condition as shown.
