I've really only loked at the AEM cam gears for H23a, but how do they compare to some of the others?
Is JG any good?

 

JG uses 6 adjustment bolts.

 

sounds like the way to go, AEM only have 3 bolts I think.
do they work with the stock belts?

 

Yes mine is stock.

 

cam gears are cam gears as long as they come from AEM, skunk2, jg, toda etc, i wouldnt buy a brand no one has used extensively


tighten the bolts down and you are fine
papadakis's old h22a had aem cam gears, if it works for a 1000hp h22a, then it would work for us
