One valve cover does not have a complete fin.
The second valve cover has extra material on the script, most noticeably on the "r" and in the "o".
These covers are in the cast finish and have been irridited. Irriditing cleans the valve covers so they are ready for many powder coating or painting processes. Irriditing makes the aluminum a dull white/light grey color.
For reference, see our regular Chevy Small Block, 1955-1959 Staggered Bolt Pattern, CHEVROLET® Script and Fins Valve Covers, Ac-cast, PML Part Number 11029.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
