Head Coach Kieran Campbell has made five changes to the starting 15, including a completely new front row and half back pairing.
Kyle McCall, John Andrew and Ricky Lutton are selected in the front row, with captain Lewis Stevenson and Neil McComb in the engine room. Ronald Raaymakers, Sean Reidy and Charlie Butterworth continue in the back row.
Ulster U20 half backs Conor Young and Sean O’Hagan have been elevated to the starting XV after impressive appearances off the bench last week. Sam Arnold, Ricky Andrew, Jacob Stockdale, Jack Owens and Peter Nelson are retained in the backline.
The bench includes forwards Paul Jackson, Dave Ryan, John Donnan and Frank Taggart, and backs David Shanahan, Josh Bingham and Rory Scholes.
A win for the Ravens would see them leapfrog Aberavon in the table.
Tickets are £8 per adult, £5 for youths and OAPs and £15 for a family of two adults and two children. Children under 10 can gain free entry. Season tickets are only valid for Ravens games played at Kingspan Stadium.
