Boyd has signed a short-term deal that will keep him with Kenny Shiels' side until the end of the season after his release from MLS side Portland Timbers.
But so far, the former Scotland frontman - the SPL's record scorer with 164 strikes - and Heffernan have managed just six minutes of action together after the former's late substitute appearance in last weekend's 4-2 William Hill Scottish Cup quarter-final defeat to Hibernian.
However, ex-Rangers man Boyd did press home his case for a start in Saturday's SPL meeting with St Johnstone at McDiarmid Park by netting in a 4-1 defeat to the Perth men's Under-20s on Wednesday night.
Heffernan, though, knows he already faces stiff competition for his starting slot from the likes of Cillian Sheridan and instead of feeling threatened, hopes to link up with Boyd in a two-pronged attack.
The 31-year-old told Press Association Sport: "I don't think Kris' arrival puts any more pressure on me. Kris is a good player but so is Cillian Sheridan, while we've got Willie Gros and Rory McKenzie too.
"Boydy has come in and I'm sure he will want to play games - but just like all the strikers will want to do.
"It's good competition and I'm sure a lot of teams in the SPL would like to have that kind of competition for places.
"We've not been on the pitch much together so far but hopefully if we do get to link up we can get a few goals and start off on the right foot."
