The Wolves captain is confident the current system makes Mick McCarthy's side tougher to break down but has also resulted in them creating more chances.
Henry said: "How am I finding the five-man midfield? I am enjoying playing like that.
"We are still creating chances, probably more so than when we were using the 4-4-2 system.
"A lot of teams play with three in the middle and there has been a definite improvement in our performances since we have gone to the five-man midfield.
"The formation suits us and is instilled in us now.
"We know the way the gaffer wants to play that formation and, definitely away from home, you don't need to be charging forward and being too gung-ho.
"That is something we might have been guilty of earlier in the season.
"We were attacking teams too much and getting picked off. We seem to have combated that - although it still doesn't guarantee winning games."
Henry believes the sparkling form of Doyle has allowed Wolves to play the current system with some success.
He said: "Kevin is fine on his own up front. I don't think he needs much help.
"I don't think we could do if we didn't have someone like him up there.
"His performances have been fantastic for us."
