Hi Roberto,
I have a Goerz DAGOR 7" (180mm, okay, technically 178mm) f6.8 Lens. I shot it on my 8x10 camera at both f45 and f64, and the lens vignetted. The Goerz literature on this lens from 1951 claims that it does cover 8x10. Maybe other versions of this lens cover 8x10: I don't know. The serial number on my DAGOR is 769522.
2 lenses that I have found in that focal length range that will cover 8x10 are the Kodak WIDE FIELD EKTAR 7 1/2" (190mm) f6.3 and the Bausch & Lomb PROTAR V 7 1/4" (183mm) f18 lenses. The Bausch & Lomb lens is tiny, smaller than the Goerz. You can read more about it on Chris Perez's website:

The Bausch & Lomb lens comes in both uncoated and coated versions, as Chris explains in the article linked above.
The Fuji FUJINON-W 180mm f5.6 lens with inside lettering is also supposed to just cover 8x10. I bought 1 of these lenses, and it also vignetted on 8x10 at f45 and f64 for me. Maybe I have bad luck with lenses covering 8x10...
The Kodak, Bausch & Lomb, and Fuji lenses are relatively inexpensive: i got mine for around US$200 each.
Good luck finding a lens that you like and have fun.
Daniel
