The Bucks head to the Tameside Stadium tomorrow, where Curzon are yet to win in National League North this season.
Cowan's side have not won any of their last three trips there though, and lost their last three games on the road.
"It's a good surface and never an easy place to go to," said the Telford chief.
"Curzon are a very good footballing side with a lot of experience at this level and they cannot be taken lightly.
"It's about us and making sure we get it right. We're playing against ourselves, really.
"Momentum is a big thing for us and we want to go up there and put on a really good show."
The Bucks, after a blistering start to the season, are on a four-game winless run in the league.
Their last outing, though, was a morale-boosting 1-1 draw with top-of-the-table Chorley at the New Bucks Head.
"A lot of character was on display but the performance was excellent as well," said Cowan.
"Chorley, credit to them, are the league leaders and they're a very good team but we matched them and a point was the least we deserved.
"We're evolving as a group all the the time and we just have to get back to what we know we can do.
"Chorley was a step in the right direction and we're looking to build on that at Curzon."
Meanwhile, goalkeeping coach Darren Acton has gone back to Solihull Moors after leaving Telford.
The former Bucks shot-stopper joined Cowan's coaching set-up from Moors in the summer due to work commitments, but now has more flexible hours so has returned to Damson Park.
"Not only has Acco been my team-mate and colleague but also my mate so to not have him by our side is going to be a huge blow," added Cowan.
"I am however ecstatic that he has been given opportunity that he feels will blossom into something greater in the future closer to home and we obviously wish him all the very best in the future.
"As a group, we will move on. I believe we have the quality within the group of staff and players to continue to thrive.”
