95 and 96 heads are exactly the same, the difference is like you said, in the cams and sprockets. There is a "check valve" in the back of the 95 cams that the VTC solenoid seats up against when it engages. In the back of my stock cams it's just a threaded plug with a small hole in the middle. I'm pretty sure I checked and I think the lift of the cams is the same, don't know about the duration though. As far as the sprockets those are of course different, mine are pretty much solid with no VTC crap. VTC sprockets usually give out when running my cams anyway so luckily I don't have to upgrade.
