You might be able to use covers and diatomaceous earth to help with your slugs. Also, I have a theory I'm working on. Check your soil magnesium/salt levels. We get lots of rain and end up with some salt deficiencies which seems to correlate with slug happiness.
The heads weren't completely dry when I pulled in the sunflowers, but mostly and then I hung them inside, where we ran the heat and kept an eye on rodent attacks. That said, I found sunflower a nice bread additive, but not a substitute. Sunflower if nutritious but falls into the fat/protein category where as corn is more grain/sugar/fiber category. If I were you I'd try quinoa. I have had luck growing almost two seasons worth of quinoa in one season in Ohio and it is a grain. If it fails, the leaves are edible. I was also able to do a late crop of sorghum here and dry that inside. It did very well and is about the same thing as corn. If sorghum fails to mature in time, the stems are a nice sugary treat. My grain corn on the other hand, planted late, is just tassling now. Just to give you a perspective on timing.
