351W (yes, a ford) cast valve covers

They interchange, been there done that.
Ok gotcha, I thought you were saying this car was a 5.0. Was kind of a confusing post you wrote up. Yeah most everything is the same between the two. Except the deck height, balancer, stroke, and intake. Exhaust manifolds are a little diffweent as well, but you are correct, bolt pattern for valve covers are same.
