Should I retake the GRE if I'm aiming for a top 20 PGR school?

I got my unofficial scores today and got 166V and 160Q. I'm okay with the verbal, but the quant score is lower than any quant score I ever received on a practice test. The verbal score also seems to be a little below average for top schools. I'm trying to go into phil. of mind/epistemology but I'm still worried that my quant scores are too low. 

For context, I attend a US News top 5 college and am a phil/cog sci double major with a 3.98 GPA. This is to say that I don't need the GRE to bolster my stats, but I'm worried that it might raise red flags. Another option would just be not to submit them at all. Would do you think?
