An impressive 4-2 victory helped move the Tangerines up to fifth in the Premiership table, with Gary Mackay-Steven's early goal setting off a run of four unanswered strikes.
As a result, McNamara was left purring about his youthful players.
He said: "Young Gauld at 17, his touch and awareness and ability is frightening.
"I see him every day in training and I know what he's capable of.
"The first question I was asked was about David Goodwillie not starting and Ciftci and Gauld coming in, but they have answered that and shown that they are ready.
"I thought Nadir was crucial to how we played, he got the ball down under control to let the others support.
"There was a lot of pleasing things there."
It was not all smiles for McNamara, though, who was unhappy with the late goals conceded.
"They got a lift with getting a goal back from a deflection," he said.
"I felt for Rado (goalkeeper Radoslaw Cierzniak) because I thought he was excellent for us, with a few good saves in the first half.
"We showed a wee bit of inexperience at times, when you're four goals up you should keep the ball moving so we made it a bit nervy towards the end."
McNamara also believes there is a lot more to come from his young side, adding: "It's coming. I think you can see there that we could have taken more chances.
"The last pass or the decision making or the finish at times (needs work) but the pleasing thing was that they are getting better with the pace and the strength they've got."
County manager Derek Adams was unavailable for comment after the match.
