This is not a new part, just a very nice part. It is the exact reproduction of the original 65-66 289 High Performance Valve Cover Set. These covers were just like the original painted 289 valve covers, but were chrome plated. They were also available as an over-the-counter option or part of an engine dress up kit. The stamping and plating on these valve covers are just really super. They also feature the correct baffles on the underside.
