In Europe where they hotrod diesel cars more than the US, the 1.9tdi's and 1.6 turbos are getting snapped up, so they are starting to mess around with the 1.6 na's.
I know jack all about turbos, get someone more knowledgable than me to double check your turbo choice.
Things I do know that give you extra margin for error:
Get a pyrometer
Arp head studs are available
One brand of 1.9tdi head gasket is usable as an upgrade.
Also, I guess you don't want to surface the head at all if warped an these vw diesels, because the cam gets pulled out of alignment due to integral cam bearings. You could maybe find a "real" machinist who could cut head for removable cam bearings then line bore cam journals, but would probably exceed cost of new head.
