As in the shafts are directional (L/R bank)?
The arms themselves are setup L/R with the dimples away from each other. I have a spare set from another engine I could try out as well.

I don't think so as they're the originals, but I never did use the stethoscope on them. Just above/below. I didn't notice anything weird as fas as wear on that side of the rockers.
Yes the shafts install only one way. There are notches in one end of each shaft. Passenger side the notch installs down and to the rear. Driver side the notch installs down and to the front.

Alright good info, I'll pull the cover back off and take a look. I think I kept them to the same side while I was cleaning the parts, but may as well check.
*edit
What would I expect to happen if they were flipped? Weird geometry, or something else?
The rocker arm lubrication would not be effective. Oil passages should be forward of the rocker pedestal, to lubricate the rocker arm under load.
Shaft Oiling passages point towards the camshaft.

Got it, that makes sense. They certainly seem to oil up fine, but I'm headed out to the car now and I'll report back.
Incorrect oiling and possible valve train tick.
I believe there is a notch in the end of the rocker shaft. If the valve cover is pulled off the passenger side IIRC it should be towards the front, facing the intake manifold side of the pedestal.
Anything is possible. I've pulled down LA rocker shafts that were burt up, and rocker arms scored.

Alright RRR says down to the rear, so I'll just double check the direction. The notch on passenger side is to the rear but I'm working on figuring out if it's up or down right now. The driver side is facing front/down.
go with it he knows. I can dig out a rocker shaft tomorrow and take a pic if necessary.

Both shafts are in yhe correct orientation, I don't think these will really help but here's a few pics for visual aid.
What oil are you using? Seems charcoal color in your pic.
Almost like it has engine assembly lube in it. I said lube.

Yeah its VR1 which is a more greenish color, and the Lucas break-in before that was dang near green too. It's likely whatever break-in oil was left added some more of that hue.
This oil change has about 15mi and 40min of runtime.

Good point, the Lucas assembly lube was also green.

I can take the shaft off again and post pics of the arms/lifter tops/springs if it may help.
I don't think that's necessary, but if it was mine, I might pull the lifters out on #8? is it and inspect the faces.

Alright fair enough. Is there a way to pull them from the heads with a magnet, or do I just have to suck it up and pull the intake?
I'm not sure. I know on some heads, you can get them out. If you're able to do it, remove them ONE AT A TIME and put them back ONE AT A TIME. Get me?

Sounds like a plan. I'll give it a shot in the morning!
From what I gather, this is normal, but some rockers can move side to side a mm or two. It's on both ends of the shaft though, so I doubt that'd be the issue as it's only cyl 8 making noise.
That’s normal. The OEM stamped rockers are sloppy.
Yeah, perfectly normal.
Sloppy seconds?
