2020 Sunflower competition

My sun flowers appear to have multiple heads, should I leave them on the plant or should I remove some ?, I thinking about the weight of the head on the stem when it does open. Some of the ones I’ve seen the heads are huge and I’m sure are quite heavy.

I cut each one when it's ready to bring indoors. Once you start cutting it encourages more flowers to come I think.

i cut one last week I think, there's another ready to pick on the same plant now.
