how much for the p72 gsr head, is it assembeld and in working condition, also would that go on my b18b to make it a ls vtec.
The parts are all there. You will need to assemble it because the head studs are under the cams. That means you'll have to put the cams back on, and the cam caps. The valvetrain is all there. You'll need VTEC oil lines, head gasket, and an OBDI VTEC ECU (GSR if you wish to keep using the GSR manifold, or other if you plan to use a Skunk2/JG manifold). You might also consider some ARP head studs.
