How to tell if my cams are stock or yz/hot cam?

I bought a 09 wr250f with a 290 kit. But would like to know if there's a way to see if they changes the cams. Thanks

My hot cams have bolts with slots that you can loosen and change the timing. Also, a paint mark to show how they were aligned by HotCams. Factory does not. I'm not sure if all hot cams have the bolts, but if you see bolts, they are hot cams.

 

Anyone else, feel free to confirm or disagree with this, but I think I'm right.

The Hot Cams intake cams have adjustable gear position. The Hot Cams exhaust gear is fixed position. Also, the Hot Cams are black colored at the base diameter and have printed words that say "Hot Cams". Pretty easy to see.
