not sure, anders, and the head in my 745 has been rebuilt twice (once due to blown gasket) since i purchased it back in '98, and neither instance was the damage this severe. and believe it or not, the only apparent symptom experienced prior to bringing the car in for diagnosis was overheating at 65-75mph; other than that, the car was pulling away from stop lights with very good acceleration emitting little-to-no smoke, maintaining very smooth running condition for sustained periods, provided i did not attempt to exceed 70mph. at that point the needle would begin walk toward the red very quickly.
price quoted on the bare head is $650 + 200 air freight; w/ valves $960.50 + 250 air freight.
however, problem is i can't find a good mechanic to do the work here in texas. sure, lots of guys claim they can do the work, but this is in part the reason i'm going into head job #3 in span of 14yrs, approx. 100k miles.
