Unless you have the facilities to repair or can find a company close to you to complete this job, your best bet may be to find another complete engine to get you back on the road.
Corroded head studs are generally a sign of a poorly maintained engine along with the percentage and quality of the antifreeze used.

Early T25 watercooled are known for corroded head bolts and even the head shearing off. The correct genuine VW antifreeze specified for your engine should have been used. They do two sorts and its the BLUE one G11. this is stressed. If anyone has the other one they do ( red ? ? ? or any other make don't just add some of the correct one. Flush out and start again. Knowing this is not a hapeth of use in your situation I know but might help others.
