will these plugs fit a fr730v kawasaki engine?????

Yes I used these on my Toro Timecutter mower with the same Kawasaki engine. They work fine.

Will this plug fit my Husqvarna Z254F 54 inch zero turn

Check reference books in auto shop or dept. for specifics accompanied to what your whip manual lists.

Is the spark plug pre-gapped or do I need to do it?

They're gapped at about .032"...my application calls for .030", so I adjusted them.
