All this means that he is set to star in France for the first time in an Ireland shirt, having previously only travelled to Paris as a standby player.
The test that awaits him is certainly a difficult one, with Ireland having only beaten France in Paris once in 42 years.
But Henry, who helped Ulster finish runners-up in the RaboDirect PRO12 last season, is not about to shirk the challenge, adamant he can still improve under the bright international lights.
"Because I have got a run of games, yes, without a doubt I'm feeling very comfortable in that place. There is more to come from me," he said.
"There's a few things in my own game that I wasn't happy with. But, you always assess the games and improve.
"When you are playing around big players, it brings out the best in you as well. Hopefully if I can play again next week, it will be my best game yet.
"It's huge, I have travelled to Paris as a 25th man before, but never got to play.
"The atmosphere is intimidating. It is going to be a really hard game. Obviously playing away from home in Twickenham, we showed there we missed a few opportunities we didn't take and the game just got away from us.
"When you are playing the best teams, it is that one chance, that one opportunity that you create and you don't take."
