[Roadsters] Rescue Head Again

[jim roosevelt]

Thanks for all the input. 
When I go to estate/garage sales I always ask if anyone has any old Datsun parts for sale.  My roadster has an "R" engine and I know parts for older cars are hard to find.  I can't use this head but didn't want it going to the recyclers without seeing if it was useful to someone.  Any idea what I should ask for it on Craigslist?  It comes with a starter & 2 SU carbs-good for parts or core exchange.  The combustion chambers are circular ( 3 1/4" diameter).  
Thanks,
Mike
