Help finding a head for a SD33T

[Norm reynolds]

Got a 1987 international scout with a SD 33 T Nissan Diesel that has a cracked cylinder head
This guy spent a a bucket of money on this thing 8.000 in body work 4000 for new engine two years ago
BUT What I have found is This is a turbo diesel and the knuckle head that build this motor used a NON TURBO head
and that why it cracked The guy that did the motor is no longer in business so jot now in our shop
I have been looking for a month now on trying to locate a tubo head for this BUT look like there are none to be found
does any one here have any infor as to to were we can find a head for this beast
