Is it possible to get fast road cams for VTEC engines, or is that the whole point of VTEC that you don't need one as the VTEC does the work of a fast road cam anyway?
That's about right. All makers have some form of variable valve lift, but most change the lift on the standard cam, the VTEC is a really nice system and very simple and reliable.
Some VTEC engines use the extra lobe to open the second valves, turning an 8 valve into a 16 valve others just use it to change the open/close durations of all valves.
