Looking for set of 930 Heads

[RarlyL8]

This may be a better place to post than the classified ads for a specific 930 part.
I'm looking for a complete set of heads for an R&D project. They must be serviceable with no damage. We are experimenting with CIS to significantly raise the fuel delivery and must build an engine that can utilize it (how backwards is that!) so the heads will be refreshed and modified.
Please let me know what you have and what you need for the set. Thanks!
