As you see, the middle plant (about 12" tall) is showing signs of flower
heads. Question is - if I remove all early heads, preventing them from
flowering in 2017, can I expect them to gain height and bulk this year? TIA.

It's generally recommended, for that reason, yes. I wouldn't rely
on it, because it may not start any new growth shoots.
