i belive the vtec system revs higher as it has variable lift controlled by oil pressure, at certain revs the oil pressure increases shooting a metal rod through a locating hole which locks into place causing a redundant valve to start working which has bigger lift

So I was miles off then

But on a normal non VVT type engine my statement at the top is correct.

the pockets them selves wont change the power band, but fitting cams with higher lift and having pockets to accomodate this lift will shift the power band yes, its only safe if ya engine is built to rev high, ie fit arps, steel rods, etc etc the higher the revs the more expensive it gets

nope.....

just allowing more air/fuel in..... but the valve is open for shorter times, meaning you have to rev faster to get all the 'potential' air in
