Yes, is that what you wanted to know? OH I see, you want to know the
difference. Well so muxh for humor....

The 44FFs are threaded all the way from the sealing ledge to the tip of the
plug. The 44Fs have the threads ending about 1/16 in. from the tip of the
plug end. This portion is smooth instead of being threaded. This was done
years ago to agree with a European spec as I remember. The plugs are
identical otherwise. Just be careful putting a 44FF into a hole that had a
44F in it because there might be a ring of carbon in the head threads. You
will need to chase the threads in the head first.
