It doesn't matter where the engine was assembled. Alloy heads have seat inserts, as opposed to cast iron heads with integral seats. The inserts apparently are hardened. Cast iron heads may or may not have the seat area "treated".
In any case, we've been using unleaded in the US for about 15 years, and no problems even with cast iron heads (the fuel companies put additives in the fuel that work with any kind of valve seat).
