Camshaft End Play?!?! How Much ?

hi that wool spacer is not for the cam, if your lobes have pits and etc, its time to replace it! when the gear is tightened up,it takes up the end play.
then there is very little or no end play. plus the lobes are ground with opposite tapers so they help hold cam in place. also the fuel pump lobe has to be bolted on front to bring things up tight.
