Im selling my JDM B16 head. Its OBD0 and the guy i bought it off of said it had approx 50,000 miles on it. It comes with B16 springs and retainers but they are not installed. He was going to do a port and polish on it but decided not to that's why its bare. It also comes with a skunk2 intake manifold. I'm looking for 350 shipped OBO. I would trade for a GSR head and I would include cash on my side if need be. I'll get pics up soon. I'm located in PA so let me know.
