    yes its possible,cam gears........a dyno almost always used when trying this and run decent octane gas 93+,start with the intake cam advance 1 deg. at a time,when optimal power is reached on the intake then you should try retarding the exaust cam, 1 degree at a time.if no power can be found try advancing a deg. or two........4 intake advance and 1-2 exaust retard is what most I've played w/so far and all I've worked w/had very minor mods....my $.02.

    on an sohc you cant retard just the exhaut valves... they are all run off of 1 cam.. which reaffirms my thought that single cams suck
