How important are SAT subject tests for Harvard?

Scores for the SAT II tests were released today. I took Latin and Literature and got 720 and 740, respectively. I plan on retaking them because I think I could do much better on both. I was wondering: how important are the SAT II tests as a part of the Harvard application? In the event that I don’t do better, should I be worried about these scores?

I have no idea if this is still his mindset, but this is what was said in the past:

That said, Harvard practices holistic admissions. Subject Tests are just one part of the equation.

Thank you! Interesting to see how they are viewed.
