Questions: Is this nut right hand threaded or left? The nut on my 134-f head won't budge. Any tricks?

It is standard right hand thread like original.

If the motor is still in the vehicle, Use the starter. Put the socket on a long breaker bar, wedge & tie it to a cross member or frame member, and bump the starter.
