Prop Declan Fitzpatrick, a try scorer in that opening tie, said: "I think we really needed to set a marker down after losing to Munster recently, and we talked a lot before the Bedford game about fronting up and stuff.
"We knew they would be pretty good coming over from England, so we were really pleased to score four tries against them in first half.
"Obviously, it died away in the second half as they got a bit of momentum on us and we were disappointed not to have put more points on them but it was a good first half and something to build on."
The Ravens management are without the services of a number of players this week, with Chris Henry, Ian Humphreys, Andy Kyriacou and Bryan Young, who were all in the matchday 22 for the Bedford game, away with the Ireland 'A' squad in Dublin.
Ricky Andrew and Luke Marshall, both from Ballymena, and impressive Queen's University scrum half Ian Porter will be hoping to make the cut in the backs.
In contention in the forwards are squad additions Adam Macklin, Ryan Fisher, Ali Birch and Thomas Anderson, along with Under-20 back rower Stephen Mulholland.
