Cylinder Head Measurement 1.9 TDI VESP

Object: Cylinder head.
Engine codes: 1Z, AHU, AFN, etc.
(all 1.9L TDI and SDI engines with Motoblock 827)

Desired measurement:
Drilling spacing between.
Center bore, injector nozzle.
Center drill set screw for tensioning chuck nozzle holder combination.

Here.

Looking at the two holes, you can see that one still contains the nozzle holder assembly, while the other has an M8 threaded pin inserted into it.

The measurement should be accurate to within +/- 0.1mm.

Is it possible to obtain this measurement somehow?

Regards,
Jens.
