I believe this is a brand new set of valve covers in their original box from the 1960's.  The box is dirty and has some shelf wear on it. This box has been sitting on a shelf for years ! The valve covers look like they have never been used. There is one very very small ding in one valve cover on the bottom corner.  It's not noticeable, but it is there and shown in the last photo. This would be a great addition to your shop man cave just to have on a shelf or just use the valve covers. Should fit all small block Chevy's 283,305,327,350and 400. Lots of photos to show condition. Ask questions before bidding.
