3sgte head needed.

So the new project 1990 GT Import , was bought with a blown head , motor is now stripped down and rebored out however the head has been pressure tested and it has failed.... too soft now. 
 
So it will require a new one , who has one for sale?
Where would the best place to start looking ?
Thanks

I have one in sydney if carmikey's is too far or what ever. You're free to come have a look any time, had a bhg (so up to you, block was used) with only 80,000k's. Gen 2.
