Ford's muscle car output in the late 1960s included a variety of now-famous engines, but one is particularly memorable: The 289ci small block V8.

In regard to engine dress-up kits, did Ford PN C4OZ-6980-A have the open-letter Cobra valve covers? What is the part number of the kit with the chrome Hi-Po valve covers?

This particular kit is no longer on the market, however, these general rules do apply to all engine dress-up parts and are not Ford specific.
