Full back Afon Bagshaw and scrum half Tomos Williams are back in the side after impressing against Italy and Ireland in the opening rounds of the Under 20 Six Nations.
Up front, Blues prospect Lewis starts at hooker, Joe Davies will make his Wales Under 20 debut at lock, partnering Scott Andrews, and in the back row, Roach and Ollie Griffiths will flank James Benjamin at No 8.
Hayward said: "This is a must win game for us. We didn't perform as we know we can against France so it's all about putting that right this week.
"We feel we have selected our strongest available side for this match; this is Jack Dixon's third season of Under 20 international rugby and Ashley Evans has recently added to his Wales Under 20 experience with a stint with Wales Sevens. Angus and Tyler deserve an opportunity to show what they can do, as do forwards Joe Davies and Ollie Griffiths getting their first starts.
"As you would expect, England are a very strong team, they had a good win over Ireland in the last round. However, we are concentrating on our own game and on ensuring our own mind-set is right on Friday night if we are to come away from Newcastle with a positive result. We always knew that we would learn most about our players from the France and England games in this tournament."
