Only three uncapped players make the 21-man squad for the 'Kick It Out' clash at Bramall Lane on Tuesday, August 13 (7.30pm).
Goalkeeper Jack Hamilton and defender Brad McKay are among six Hearts players in the party and they are joined on the coach south by fellow debutant Stevie May of St Johnstone.
Stark has also included Aberdeen defender Ryan Jack, Dundee United midfielder Stuart Armstrong and Celtic striker Tony Watt, who were involved in the Scotland senior squad which beat Croatia 1-0 in June.
And Stark insisted May's current form with St Johnstone, which includes goals against Rosenborg and Hearts, made it impossible for the striker to be overlooked.
"I've been watching Stevie for a number of years as I do with all the young ones. His form and goalscoring right now is too good to ignore.
"He is confident and is born in 1992, so is one of the more experienced ones
in the group. Put all those things together and that is a nice mix for this game.
"His goalscoring record at Hamilton and Alloa was exceptional. At Hamilton, he
was playing a couple of leagues up from Alloa and now he is in the top division
and we're talking about whether he can keep scoring."
