The engine in my car had used chrome 426 valve covers installed by the prior owner when they rebuilt the engine. I would like to replace them with the black wrinkle finish ones. I can get the chrome ones powder coated in black wrinkle finish for $40. They need minimal prep to the surface no pitting or rust. I do not know if they are Mopar performance covers or just aftermarket ones; since they do not leak they are a good candidate to reuse. All the original ones, I can find are either pricey and/or still need to be repainted. Any advice on this?
