Just leave it off and use the NF-12 parts instead. It's a very simple fix. If you've already glued it, yes you'll have to cut it off.
The nose of the NF-14 *looks* longer due to the shorter, steeper winsdcreen, and the widened (and shortened) intakes. John measured one (while researching his 1/48 kit) and found that it's the very same length as the NF-12.
