All sunflowers produce seeds if they are fertilized. The only way they would not develop seeds is if they were pollenless and there were no sunflowers with pollen within range (about 3 miles for a honeybee) to fertilize them.

You need to be growing the proper species. Not all of them will grow that tall. Look for "Giant" sunflower seeds.
If the sunflowers are not a hybrid variety, then you can save the seed by cutting the flowers when the seeds are fully formed and loose in the head, drying the whole head for two or so weeks, rubbing them from the head, drying for a further couple of weeks, and replanting in the spring. you can use hybrid varieties as long as long as they are not sterile in which case you wont get any seeds anyway. you just wont get the same flower vigor and or good looks. zaf.
