What Subject Test Scores Should I Send?

Here are my SAT II scores:

US History - 750
Latin - 670

Should I send both scores to colleges, or just the 750? Will sending the 670 on Latin hurt my admission chances? Does sending certain scores depend on how selective the school is?

I am applying to:
Harvard
Brown
Northwestern
UCLA
UC Berkeley
USC
Pepperdine
BU
Ithaca

So, should I send both scores to every school, just some, or none?
I know that there is a heck of a lot more to an application that two subject tests, but I plan on sending my scores soon and just want some guidance on this.

Thanks.
