DML FAQ : Engine : Are Mopar Performance Magnum V6 valve covers available?
Mopar doesn't make a set of valve covers for the Magnum v6. But they do make a chrome set for the premagnum v6. The premag actually has less bolt holes in it then the mag, the valve cover is also shaped a little differently as to where it looks like there might be a sealing problem on one corner. It is possible to make it work but it's not a direct bolt on. Also, the premags have rail rockers instead of the individual rockers. This is why the valve cover is shaped weird. The premag valve covers just plain looks funny, the magnum one is much more pleasing. Your best bet for trick mag v6 valve covers is to buy a set and have them chromed of painted.
