After some more searching this is what I found. I know for a fact that I have the y8 head but I think I have the z6 adj. cam gear which is this one.
The Y8 cam gear should look like this
notice how the grove for the key is off by around 4 degrees
This would lead me to believe that if I was using a y8 bottom end I would have to set the cam gear to around 4 degree advanced to get the stock timing for d16y8.
In my case, since I have the d16a6 bottom end, Should I leave the markings at 0? or what? thanks
