Hello I will help you with your question,

The intake cam has the nub the cam sensor reads, it is on the transmission end of the cam.

Let me know how I can help, (pictures of that end of the cams would help)

Thank you

The transmission end of the cam shafts look identical. The cam sensor is on the front of the engine

Can you see where the nub is that the sensor reads? That is the intake cam.

The thrust area should be in a different position on each cam as well so they only go in one position.

Can you post a picture of the cams side by side?

One cam has 2 sets of numbers stamped on it.R90400056. The other set is GC44. Is this the intake or exhaust?
Expert:  George H. replied 11 months ago.

Sorry the numbers are not part numbers nor do they identify the cams. Can you post a picture of the cams side by side?

Customer: replied 11 months ago.
The engine has GM stamped in several places. I assume these GM numbers
Expert:  George H. replied 11 months ago.

They are manufacturing numbers not part numbers so there is no way to identify them from those numbers.

Can you post a picture of them side by side?

I"m driving at the moment , but sent pictures a couple of days ago. Wil send pics again when I get home.
Expert:  George H. replied 11 months ago.

I am not sure where you sent pictures? You can use the paperclip icon on the toolbar to attach them to your post.

Thank you

I found another post that has the R90400056 as the intake cam and the engine was running so I assume it is correct.

Please let me know if you have further questions

Thank you
