You don't automatically get any gain at all with running a vernier, mostly on std cams dialling around either side of std will do little if anything for power.
They are more suited to more aggressive cam profiles, the power point can be shifted around by moving timing even on std, but makers are pretty spot on these days, I wouldn't even consider one for a std engine/cam.
