First off: hello all!

I'm posting here (hopefully correctly) for help with a question that I have. I've searched and can't find an exact answer.

I have an xterra with a ka24de. I've had to get it rebuilt, so know I'm in the process of reassembling it. I did the cam swap from a 96 Altima since mine were bad and these were readily available. I have the dowel pins and sprockets lined as per JWT info. I had to move the cams while they were installed to get everything lined up correctly.

My question is this: Is it ok if the intake valves are open on the number three cylinder and the exhaust open on the number two cylinder? All others are closed.
I've attached some pics, I know it's a little hard to see. Any input is greatly appreciated. My apologies if this is a dumb question. I'm just always worried about something messing up. Excuse the mess in the background on the first pic. Lol.
Second pic is exhaust side and third is the intake side.

Do they move to a closed position when you rotate the cams back a bit?

If they aren't stuck open and the cams are phased properly, check the timing marks, different colored links on the timing chain corresponding to dots on the three sprockets, it should be fine. You might want to very slowly rotate the engine through four full rotations to make sure nothing is hitting anything and that all cylinders are opening and closing valves in the same manner.

Yeah everything rotates fine and open/closes without hitting anything. Piston one lobes are pointing out and away from one another.
