The way things are going we will have to say climb Flight level 140,on 1013 millibar/hectopascals.
We have to say degrees (best practice) to helis that have spent their entire trip below Flight levels.They introduced degrees after headings that end in zero,but completely forgot about quadrantal levels.It's just more and more confusion,when splitting the instructions is far safer.
Surely the word heading means what it says.
