Heaton is in the final stages of recovery from a long-term shoulder injury, although Dyche has refused say whether he will return to replace Pope immediately.
Burnley are not short on goalkeeping options, with Anders Lindegaard signing a contract extension on Thursday, and fourth option Adam Legzdins also on the squad roster.
Dyche said: ''Tom knows the job, as does Anders and Legzdins behind them. Goalies know the script. Whether you're first choice, second choice or fighting to get involved, that is just the lie of the land with goalkeepers.''
The Burnley boss also commented on Pope's performance in Heaton's absence. He said: ''Pope is doing nicely, he's playing well and having a good season. Tom has been a fantastic servant over time and Anders and Legz are still looking to earn their spurs here.''
He added: ''There are four very good goalkeepers - two obvious ones. Nick has currently got the shirt, it is my decision if that continues over the season.''
