New head is here
The new head has arrived, from the eBay seller in Texas. $250, including shipping both ways (yes, you need to return the core no matter what its condition). Excellent packaging job by the seller. I bought the "valves only" version, so tonight I plan to move over the cam, liters, rockers, etc. from the old head to the newly rebuilt one.
