Default 92+ exhaust manifold on a 94 L67

If I need to replace my exhaust manifold, can I use one from a non-supercharged engine? Does it matter if the donor car has a 2.25" or 2.5" exhaust pipe?

I don't think engine matters, but year does. 92 had a different EGR tube thread type than 93-95.

So any Bonneville engine from 93-95 with a good exhaust manifold will do?
