For superchargers you just need to change the pulley size, a smaller pulley will spin the blower quicker therefore produce more boost. The Vortech V1/V2's will go to around 20psi (if you really need to) or about 1000cfm which is enough to support 680hp.

The roller rockers used in the 200kw engines are branded Ford but made by Crane. Ford has used crane to manufacture their roller rockers for years.

roller rocker is only relevant on a pushrod engine.. it sits on top of the head and its what levers between pushrod and the valve stem..(coz the pushrod is more or less paralell to the valve stem and when the pushrod comes up the valve has be pushed down)

roller rockers(as opposed to standard rockers) have little rollers where they touch the valve instead of just plain metal rubbing there..

its a DIY job... about the easiest thing to do involving oiled parts.. coz on a ford v8 the most you have to take off is the upper intake(just make sure no debris falls down there) and the rocker covers..
