327amc,
First off, Welcome to Stovebolt!
Your picture posted just fine. It doesn't actually display until you complete the post process (doesn't show in the "preview" mode).
Otto's suggestion about providing pictures and details about your engine will help confirm what you actually have.
That being said, the part number you noted does match up to a 1951 235 (and 216 as well), but appears to be just the plain cork gasket set currently available from every vendor I could find on the web.
I tried searching to see if I could find a vendor that offers the set with the formed neoprene end gasket pieces (like the ones in your picture), but found none currently available. Other vendors may have gaskets that have a better form/shape, but all seem to be the very same thing you have from your vendor. It may have been poorly handled/stored to cause it to deform from its original shape.
The cork gasket material does provide some flexibility to mold to the engine block and pan sealing surfaces, but will need some gasket adhesive to keep the needed shape and placement when you reinstall the pan.
AM sure that others will come along and chime in with more information as they can.
Dan
