The Edinburgh Gunners second row, who moves to Glasgow Warriors to play next season, said in the Evening News: "We got a wee bit of a rocket during the interval which was fair enough because in the scrums, for example, we were not as tight as we should have been for a set unit."
Although not a perfect display by any means, the result left Ally in upbeat mood ahead of the squad's departure on Sunday for the two-Test tour of South Africa.
Ally said: "What was pleasing, too, was the fact we found things to work on. Overall, we had to be delighted with the way we learned to convert pressure into points, which hasn't always happened."
Of the nine tries, no fewer than eight came from the backs and that augurs well for the type of all-round display that will be needed to beat the Springboks in their own backyard.
Ally added: "I'm struggling to think of an occasion when we went looking for a score and returned to our half empty-handed.
Ally also had words of encouragement for the likes of Glasgow's Donnie Macfadyen and Kelly Brown as they battled for a Test vacancy in the back row.
"With Donnie coming off the bench at half-time [for Jason White] to link up with an in-form Kelly there is added competition while Scott Lawson and Dougie Hall threw equally well to an improving line-out in separate shifts.
"So, although we are going to South Africa as underdogs that term can sit comfortably with us in terms of creating an upset in the eyes of some.
"Why not? Under Frank Hadden we are learning to believe any win is possible. Having already beaten France and England this season we can certainly be competitive, even in South Africa."
