You may try

   proxy_method GET;

in a server/location dedicated for synchronization.  It will cause 
nginx to use GET requests to upstream (though it won't sent 
anything to client as long as original request was HEAD one).  
This is basically identical to what proxy_cache does with HEAD 
requests.

BTW, proxy_ignore_client_abort is meaningless with proxy_store, 
as proxy_store activates the same logic unconditionally.

The "proxy_cache_methods" directive exists and not deprecated.  
It's for proxy_cache though, not proxy_store.
