But OTOH, if you can restore things to spec (blueprint & balance), why can't you reset the pin on the cam?
It achieves the same goal. Realtive cam (Cam to Cam) timing should not change.. That would be the reason for the offset key. otherwise you would have to setup both cam gears with two offset bushings identical. That sounds alot more complicated and expensive to achieve the same goal as a simple offset key.
