Or you could just order a second one for the exhaust side. All you are really doing without having aftermarket cams in there is changing your power band. At 3 degrees advance it probably feels stonger on the bottom end and you don't feel as much on the top end. At least that's what mine did anyway. Have fun playing with the cam gears. If you have the instructions for the gear you can adjust it yourself if you know your way around a set of tools
