This is a well debated subject and with all due respect I disagree it is not that important. I too have been doing this for a while. Cam timining difference like this will change AFRs from side to side. Up to a point. Now on some motors that may not make a difference, but on some of the ones we build one point is a difference between lasting or putting a hole in it. It also makes for a smooth idle and better throttle response. Same theory and the reason we sync webers. You want both sides to draw the same. The owners may not notice the difference but I sure do and take cam timing to .01 if I can. Porsche felt by the 993 that it wasn't a big deal and used simple lock in tools. We have had to correct more timing errors and strange idling problems then I would like to admit. The common issue with a 993 idling poor is an uneven cam timing. This and a 1.25 will buy a cup of coffee and that's about it.
