I agree there's no difference, if the width is the same.
I can't believe a local Building Commissioner will issue a Building Permit for a renovation, without a certification as to what's actually in place.
With respect to "tilt up", it's a horse of another color. In theory, the header should be the same, but there are other considerations. What's in those walls? Conduit? Plumbing? HVAC ducts? Was the concrete tested when poured?
I'll defer to a structural engineer on this part of the equation, because I'm certainly not one (& only do Commercial construction, which means we need a "stamp" to do anything) ... but with pre-cast concrete, it seems we're looking at an entirely different scenario regarding torsional strength. I'm not sure a "header" for a window (depending on the size of the window), works for a door. (i.e. the precast is going to have rebar below the window RO).
