No personal Exp on the Z6, but Id put 20bucks on stock.

ya with stock cams probably the stock point.

If you really want to make sure though if u have a VAFC go to a dyno and try this.

Set your vtec point at 8000rpm do a dyno pull
now set your vtec at 2000 rppm and do another pull.
Lay the graphs over one an other and make the vtec point where they cross..

yes, crx88si is the master, that's the best way to do it.
