Hello and welcome, yes the cams set at 10 and 2, the intake cam has a mark that is marked intake, the exhaust cam gear has a mark exhaust. as long as the crank gear key way is at 12 oclock, also the timing mark on the crank gear will be at 5 oclock.

Install the crankshaft sprocket with timing mark at the 5 o'clock position.

  • Install the intake camshaft sprocket with the INT diamond at the 2 o'clock position.
  • Hand tighten a NEW intake camshaft sprocket bolt.
  • Route the timing chain around the crankshaft sprocket with the matching colored link aligning with the timing mark.
  • Route the timing chain around the intake camshaft sprocket with the uniquely colored link (1) aligning with the INT diamond.

    The gears can be placed on the cams in two ways, rotated 180 degrees they still fit so placing the cams properly is the question I have
    Expert:  Goodwrench9124 replied 4 years ago.

    both cam gears are the same, only difference they have markings to set the timing intake or exhaust. and they should only bolt on one way, the slot on backside the gear is offset ed just slightly so they only bolt on one way.
