I have this 80gallon tank Divided into three but im using only two spots they both have a flower horn but my question is it possible that if one flowerhorn kok is beigger will it shrink the other flowerhorns kok because i have a red dragon and a malau they are all ways looking at each other but my malau's kok shrunk and my red dragon grew.. do i need to but in a difrent tank OR ..? Im feeding him Sumo red and market shrimp sometimes.. Let me know what you Have for me.. Thanks

1 fish per tank = best growth and biggest KOK. You could put a mirror next to your fish for 1-2 hours a day (don't overdo it) and it should stimulate aggression/dominance which will improve it's head size. You could also try a female parrot if your male won't kill her. Remember the head is only going to grow as big as it's genetics allow it to. Start with high quality fish and you won't have to worry about head growth. If your fish was a $5 bargain from the LFS it's probably not going to grow a big head.

Dominance plays a role for your fish here. I guess one of your fish feels more dominant than the other, and yes this can have effects on your fish's kok growth(colors and the fish itself also). I usually keep them single by themselves or with a male blood parrot(if you don't want them to start breeding) if possible for such tank mates.
As far as your feeding goes, your on the right track. Just avoid the imitation Grand Sumo out there.
