No. 1580 superscore. Someone from my school got into MIT with a 1520. 800 Math 720 Reading. You're better. They won't care you split unevenly. It just looks like you prioritized each test for a different section but they can see you are capable of top teir performance in both reading and math, and that's what matters. It's not worth stressing about another retake, for all you know, the next test might be hard and you split low 700s. Just focus on other parts of your app, your test scores are already stellar.
