NOS slant six exhaust manifold

Wish I would have seen this before ordering a "Dorman" for like $260... my new maninfold is a pile of crap... I just got finished modifying it so that the heat box will actually work. The exhaust ports are smaller than the original. BTW, it says made in China. (Did I get ripped off, are Dorman slant 6 manifolds not made in China?) This NOS has to be worth more than $300...
