Not brand new but they look it. I bought these because I didn't have any and was planning on building another motor but plans change. Someone installed these and then must've pulled them right back off. They did have a spattering of oil on the under side and there is one small nick about the size of a pencil lead. Also there is some slight discoloration on one of the rails and up the side in between the bolts(kind of a golden hue). Not sure what it is. Almost like it was colored by heat. Just saying they aren't absolutely perfect. They were still in the GM Performance box when I got them. I've never held repops but these seem too thick and nice to be anything but GM. Came with AC oil breather cap. $150 shipped. VC BOX covers
