Quins had shocked the Irish giants in the semi-final at Thomond Park despite having Nick Easter red-carded - and they will head to the Cardiff City Stadium full of confidence.
Having been spared further punishment for his indiscretion, Easter retains his place in the side, while Nick Evans has been passed fit after struggling with a knock.
Tomas Vallejos has not been as lucky, though, with the Argentinian lock being replaced on the bench by Peter Browne after he broke his thumb in the semi-final.
Like Easter France prop Rodrigo Roncero has been spared a ban so he takes his place in the Stade Francais front row for the clash.
Roncero was cited for a late body check on Morgan Parra in the semi-final win over Clermont but he escaped further sanction.
Flanker Antoine Burban comes into the side after recovering from a cut, however Scotland full-back Hugo Southwell and France hooker Dimitri Szarzewski are both ruled out through injury.
There is a certain English feel to the Stade squad, with James Haskell and Tom Palmer both starting and Ollie Phillips named on the bench.
