i want to change the cams in the 91 saph 2 ltr twinky to help it rev abit more freely without loosing torque ( talk about wanting your cake and eating it )

does anyone know a good company that can either regrind cams or know of a company that doesnt charge £500 per cam ?? as i'm trying to do it abit cheaply as the recession is still squeezing me a little

also if i was to change my cams what would i need to change/modify/upgrade

also i'm thinking about lightening my flywheel does anyone know where i can get it done and again is there anything to look out for if i do so ?

all advice welcome
