Nathan Lowndes and Billy Paynter scored the goals which saw the Valiants to a 2-0 win at Vale Park.
Bur Foyle, whose side visit Glanford Park next week, felt his side were hit badly by injuries.
He said: "We'll take the three points and run. We've had a miserable time with injuries but in terms of points it's been a magnificent week.
"I thought we were poor apart from our two strikers (Paynter and Lowndes) who worked their socks off and deserved their goals.
"I have to be delighted that we have beaten a very good side and have 14 points from seven games."
