Up front, Dragons prop Aaron Coundley will start at loose head in place of Dan Watchurst, while James King moves to lock from the back row and Cardiff's Jake Thomas will start on the blindside.
Reserve squad players Justin Tipuric and scrum half Tavis Knoyle have been called into the Six Nations squad and will start on the bench. Tipuric was a key member of last season's Under 20 squad and returns to the squad after a period of injury, while for Knoyle, an appearance would mean a first Under 20 cap.
Davies said, "There is huge determination from the players to perform well at Bridgend on Friday night and get a win against England.
"While we were disappointed with the result on Friday night, we were pleased with the effort shown and with the maturity the boys have shown since the defeat and I'm sure they have learned a great deal from the experience.
"We have chosen some new combinations behind the scrum for this game that should give us an extra dimension tactically.
"James King was arguably our best player against Scotland and his move to lock, along with Aaron Coundley's inclusion should give us some extra intensity and mobility in the front five.
"Added to that, the changes will mean we can blood some more players during this championship which is important as we move towards the Junior World Championship.
"The ultimate aims for this management team are to give the players a good grounding in what it takes, not only to be successful as a team, but to develop them into potential regional and international players."
