If that part number is for a SB Mopar I don't think I've ever reused them, if it is for BB I have reused them(8519, 1009 and some others part # mabye confused) after dyno testing and even after driving them on the street and reusing them. They showed no damage and they went back on the same side with the same side up with the same heads shruggy work
