Figure 1- 10 chain links from intake dot to exhaust dot- Valvetrain after everything's re-installed. Notice the number of chain links from the intake sprocket punch mark to the exhaust mark.

There are 10 links in between. Also verify that the dowel notch on the sprocket is pointing at about 10 o'clock and 12 o'clock for the intake and exhaust side

The cam and sprockets should be in the exact same position as shown in Fig. 2b

If there isn't exactly 10 links or if the position is off, you will need to re-adjust the sprockets and cams to get it perfect. Do not proceed to the next step unless you are sure the cams are lined up correctly.

Pour some fresh oil over the newly installed cams. Put the transmission in neutral.

Using a ratchet, hand crank the engine carefully to make sure the cams are installed correctly.

If you feel any resistance (ie, the engine won't crank), STOP and double check everything again.

Once you are able to rotate the engine a few times, you can re-install everything.
