Gotta sell these to finish my swap. I was going to use them, but I currently don't have the cash to buy new valve springs and retainers. I paid $500 for these, and they have never been used or even unwrapped from there plastic. I'm asking $400 firm for them, I need these gone asap. Only thing I will trade for is a mint GSR or b16 tranny, but really need the cash to finish my motor. Text me @ 772-501-2676.
