The header height will still function ok. but you still need some type of divider to direct the crop. You can still find the short dividers from early series heads, If I were you I would give the long ones a try. I have used both and the long dividers work the best, they are adjustable up and down and they can be shortened some. look at the head manual and it will show you how to shorten some. I would also use the header height control if you have it, it will take a lot of work off you if it is set up correctly. good luck
