These are original steel "Chevrolet" script valve covers I had chromed several years ago for a project that I eventually sold. They were as perfect as you could find when I sent them to Advanced Plating. These are heavy steel, not tinny Chinese re-pops. These are correct for Z28 & SS small blocks. There are no holes for oil or PCV. $300.00 shipped in lower 48. (910) 308-0130
