Panteras all came with plain Ford Stamped Steel Valve Covers painted Ford Blue & some, I believe on earlier ones, had a rectangular finned aluminum "DeTomaso" Plaque glued onto them.
The cast Aluminum "DeTomaso" Valve Covers are aftermarket.
Mangustas came with plain Ford Stamped Steel Valvecovers with a DeTomaso aluminum "plaques" glued onto them that were kind of "L" shaped.
