Stock cams have numbers with arrows on them for timing. New style hotcams have little dots that are punched into the cam sprockets, old style hotcams have painted on timing marks with no auto decompression mechanism on the exhaust cam. Hotcams are timed different from stock cams also. There are 14.5 pins between marks with hotcams and 15 with stock cams.
Here's a pic of stock cams timed this is with the line next to the T on the flywheel lined up in the inspection window. The the 3 mark pointing up on the intake, 2 mark pointing up for the exhaust and the T lined up on the flywheel. The other marks should be parallel to the head. My timing chain was stretched making it off slightly in this photo.

One of old school hotcams timed and with the line next to the T on the flywheel lined up in the inspection window. And a new timing chain.
