I think the aggressive Mega and Web cams are the best performers but the drop in Hot Cams represent a good compromise between price and performance. The Hot Cam stage 2(or 3 as they are now calling it) is a great top end cam and coupled with a big bore high compression piston, full exhaust and aftermarket CDI gives a great performance gain. If you want to take it a bit further you could then go with a FCR, Edelbrock or 450R carb. Here are some specs(lift and duration) on the different 400EX cams:
