Engine wants to die at stop lights

I'll give the clothespins a shot. It makes sense since I have the Headers installed it brings the heat up inside the engine bay. What is good to use on the fuel lines to insulate if this does end up being the problem? The Carb is a Street Avenger 650. Car runs great during normal stop and go operation even at the track I didnt have any trouble even doing 4-5 runs in row.
