repair co for 944 turbo cylinder head

[DKL]

Can anyone recommend a specialist welding co who might be able to repair my head? It seems to have a number of holes in the mounting surface to a max of 4mm and about 10mm across.
It'll need repairing, crack testing and skimming.
Thanks

Thanks Simon, it's going to South Cerney engineering this week for their opinion but I'm not hopeful.
Trying to find out for certain the difference between 1R and 2R casting numbers.

This is the sort of nerdy thing that I might know, but don't. Had you tried Jon Mitchell?
