Where to find a Mazda Mx-5 1.8L cylindar head in Greece?

['87 Turbo II]

Hello, my name is Chris. I don't live in Greece, but a friend of mine from Greece contacted me about finding a replacement cylinder head for his 1.8L Mx-5. I live in america, and only speak English, but basically what I am getting at is I don't know how to help him. So if anyone from Greece out there knows where to find one that is a little cheaper than a new unit, please respond here and let me know. Thanks.
