This 1955-1963 Chevy Corvette Impala 283-327ci Offset Staggered Script Valve Cover is an original used GM part. Notice that the bolt holes are offset or have the staggered pattern. The image here is a sample valve cover but the one we send you will be in the same good used condition with some minor dings. Once you do a good media blast and fresh coat of paint, it will look like new.
