Anyone eels want to jump in?

I found this over the weekend:
Head studs.....all Z6 but the last one by the v-tec needs to be a Y8.
You have to use the Y8 cam and cam gear or the timing will be off.
You can use either Y8 or Z6 head gasket, Y8 I guess is the better of the 2.
You will use the Y8 timing belt.
You need to use all Y8 internals for the head.

Things I am not sure of are:
The lower gear on the block I am guessing you use the Z6 even thou the part # is diff then the Y8.
