What is a set of heads worth?

[2002_red_gts]

I was thinks off selling my stock arrow rebuild heads off my 02 gts to finance the rest off my head and cam swap. How much is a set of heads with about 2500 miles on them worth?

Typically $700-$800 if you're willing to wait. $600 if you want them gone quick
