I've seen 2.5 16v heads go for $600, 3.0 16v heads for $1200! Don't even get going about 2.7 8v heads, you have n/a, s2, 951 and 968 guys all over them for 3.0 turbo conversions!

He currently has a 16V 928 head (pretty much an 8V 944 head) at his shop, looking to see how far he can push the limits.

Putting valves from one make to another is completely different than bolting heads. The cylinder spacing, bore size, bolt pattern, water jacket, are most likely all different. It will probably be easier to make a prototype head out of a piece of aluminum than to try to drill the head while missing water jackets and intake/exhaust ports so the head will even bolt on.
Get a good CNC source, replicate a good head design, and replicate another head is probably the only way to make that work. There are places in China that can take on those jobs inexpensively (comparatively) but you will need to make a quite a few of them for it to be cost effective as the fixed costs are very high (very expensive first unit) while the main variable costs are very low (cost of aluminum, labor, and usage of proper machinery which has been absorbed by the factory).

Hacker-Pschorr Why not, friend of mine is known for making seriousally sick VW motors rebuilding the heads with huge Chevy valve's.
