cam stampings

Lay them in place with the notch in the front cap lining up and then look for the chisle mark at the back of the cam to match as well.
Once you think you have it, look at the lobe phasing and verify it makes sence.

Also -- think in Italiano (not English) -- "A" is the abbreviation for Aspirazione = Intake, and "S" is the abbreviation for Scarico = Exhaust.

 

You can also degree the cams to confirm the right sticks in the right places and that your marks are spot on and or that your eye is good enough to nail your cam timing.
