Aftermarket ones should be market on the top of the stud. That is how I found out mine were not stock

^This. If you can see a stud/nut instead of a bolt head then they're not OEM.

Also there is a good chance it will say ARP on the top of the nut/stud.

To get visuals of the studs/bolts, that would require me to remove my valve cover correct?

Sorry for the nooB questions.

That is my spare engine that I bought a while back.
I will be replacing my valve cover gasket this weekend and will be taking a picture of that to see if my current engine has aftermarket studs or not

Need to focus in on the bolts/studs under the camshafts.

Probably another bad pic, but these are the only two I have.

These are pictures I took half a year ago from my spare motor. I will get motor shots by tomorrow of the engine that I more interested in knowing than this one.
