i've read that the head gasket thickness affects timming, but cant get a grasp on it. if you go thinner than stock, i think you have to retard timming depending on how much thinner...n if you go thicker, vise versa... or something like that..

i figured that the distance from the crank to cam will differ but how would that affect timming when they are spinning at the same rate ( i know cams spin half as fast)... you know what i mean. also, i dont think its the belt, for its got the same # of teeths and the tensioner will take up/ give slack as needed. the BELT distance from the crank to intk cam should be the same right? cause of the tensioner.

im just asking so i can futher educate myself.
