If you change the cams you essentially lift open the valves higher (lower) and/or for longer. Without changing the Ecu map you won't gain 10bhp. I know because I've done it.
You can have a real faff setting up the correct cam timing (may need verniers at £200!) and you always have the very very tight clearances between valve and piston to consider.
You are better off thinking about handling and braking or (if you must have more power) find a 406 coupe V6 manual, buy it and then spend 100+ hours making the engine/box/clutch/ecu/cooling system etc fit your 306.
Once complete you'll have more torque at 1650pm than a '6 generates anywhere in the rpm range.
oh and it will sound AWESOME! :-)
