Based on the 2015 test scores, a 660 in Literature equivalates to the top 58 percentile and 710 in Math II is the top 50 percentile. (https://collegereadiness.collegeboard.org/pdf/sat-subject-tests-percentile-ranks-2015.pdf - accessed in May 2017)
I would consider retaking the subject tests if you think it you have a good chance of significantly improving your scores and therefore strengthening your application.
