Re: Prelude Cam Gears Question (SohcPower93)
If he doesn't have cams' then I don't think he can adjust the cam gears, but I may be wrong. But say if he can adjust them I think what works best on an H22 is retardting the exhaust 2 degrees and advancing the intake 2 degrees, (-2, +2). Someone with more knowledge help me out here.

My question is can aftermarket cam gears be adjusted on stock cams?

what powerband are you tuning for? midrange or top end?
if your going for midrange you would want to reduce the overlap/Lobe seperation angle, you can do this by retartding the Intake cam, and Advancing the exhuast cam
high end you want to tighten the LSA/ increase the overlap, by advancing the intake cam and retarding the exhuast cam
you retard/adv each cam by 2 degrees till you get no further gains, then you go to the next cam
you also need to re-adjust the timing after adjusting the camgears
