Wanted to borrow: Turbo 20V head

20V listers,

I would like to borrow for a week or two, a 3B, AAN, or ADU loose and
stripped (valves in place, OK) head for measurement purposes.  I wish to
quantify the hole locations for the exit water manifold used on these
engines, over and above that of the 7A.  The ultimate purpose is to be able
to easily machine these additional holes into a 7A head, thus making the 7A
useable as a replacement head for any of the above turbo systems.

The measurements would be performed with the head positioned, intake surface
up, on a mill table and, using the mill's digital position readout
capabilities, accurately determine hole center locations relative to the 3
water manifold bolt holes common to all 20V heads.  The resultant machining
instructions will be posted for all.

Anyone have a spare head lying around?  West Coast location preferred.
Any better ideas out there?
