Well you only need the head, manifold and the fuel rail, as i'm sure your aware the inlet plenum will bolt straight on.
The whole lot shouldn't cost more than £60-70 for the bits, as for shipping I don't know, I would have weighed a head for you but I got rid of all my bits, I can't see it weighing much more/less than the JDM head.
It all depends on how fast you want it, if it goes by boat it will take ages but it will be cheaper, just get the sender to write happy birthday on it to avoid import tax!
