Maybe get a price on a short block from Metric and have the Head rebuilt locally (with you supplying the new valve springs and valve stem seals so that you get good quality ones). The camshaft you can deal with yourself. You should be able to see if the cam lobes are in reusable shape and the bearing journals should be easy to measure.
A short block would mean you would probably need to install the timing chain also.
This leaves the turbo, IP and fuel injectors to decide what you want to do with also.
