Hi,
I am not sure I understand. Indeed, maximum row height in Excel is 490 points, and that is exactly what FlexCel will allow.
If you need more, you could always merge some rows, for example 2 merged rows will allow you the double of row size. While Excel won't autofit merged rows, FlexCel will.
But what the original post was about, was about printing a part of the row in one page and another part of the same row in the next. This is how Excel works too.
What would you like to change / workaround?
