I currently own a VS S2 V6 Manual Commodore with 1.9:1 yella terra (YT 6651) roller rockers. Just wondering if I were to purchase and install the stage 2 comp cam would I have any problems with lift clearance or would I have to revert to a lower ratio? Al

You would have to revert to a lower ratio. Assuming that your cylinder heads are standard then I would stick with the factory rockers. You would have to revert to a lower ratio.
