If it's close at infinity, the OP would probably be fine using it at portrait distances.

I get vignetting on a full plate, so I imagine the longer side of the 8x10 will have it a lot worse. I've never shot it on an 8x10 sheet film, just aluminum and glass plates.

But for a $50-100 Russian Tessar-knockoff, it's a good bargain.
