How much are you looking to get out of the cams? I honestly don't know what a fair offer would be on these. I would hate to insult you with a lowball offer.
I have no idea honestly all I can really find online is stage II and up and they are 1200 for a top end kit all I have is the cams them selves so I would think around 400 but I am willing to budge I have absolutely no use for them any more so just hit me up with an offer
