I have a built GSR head, it is a 95, it comes with all valvetrain, valves, vtex solnoid, and everything else that you need. It has all Skunk2 valvetrain thoughout the whole head. The head is a strret/race port and polish done buy Rage Motorsports in Corona Ca. The port and polish cost me 550 alone, and the valvetrain installed cost me 450. IM asking 850 obo for the head. I have pics.
