If i normally eat 1,060 calories a day and i start eating 1,140 will i gain weight?

Negligible : 80 calories is negligible for most people. Your body also looking needs to see calorie variation to keep your metabolism reed up. The same amount every day will slow it down. Keep it guessing by averaging your calories out over three days. Some days more, some days less. Also check out the 5-2 diet plan and try to eat clean 80% of the time.
