Flat lobes and stripper glitter oil aren't "myths", I just pointed out if someone wants to use a stock camshaft for whatever reason he would be best served using a Ford camshaft, all things being equal. I trust OEM materials generally speaking, more than aftermarket stuff. Just sayin'. Carry On.
A friend of mine spent a fortune completely re-manning a 410 MEL engine for a customer. Bored, new cam, ect. He didn't use break-in oil at start up, and wiped everything out. By everything, I mean bearings, crank, cam, everything. It looked like someone dumped metal shavings in every part of the engine. The heads were full even of shavings.
The myth I was referring to was aftermarket cams being junk. It entirely depends on the break-in procedure being done correctly with good assembly and proper oil being used. Good luck finding a NOS cam boss.
I just pulled my cam out, the bearing look excellent, and I removed the heads and you can see a little cross hatch, I’m beginning to think that the previous owner saying it was never rebuilt was not true. Or at least not to his knowledge.
I have attached the pictures of my cam, it looks okay to me but I’m a beginner. The pictures are the few concerning spots I have, there’s the small areas that look like chips but also look like it was cast and ground that way. I don’t know, and then there’s the dark spots.
Two lifters were collapsed. The new ones I have are slightly taller on the outside, but when you look at where the pushrod sits, it looks to be correct. How can I measure this to be certain?
Edit: my crankshaft spacer is also stuck. Is there any way to remove without cutting it and without using a claw puller? Or do I have to go on the 30min drive over to the auto parts store to rent one
Cam wear looks normal. But unless you stored the lifters in the order they came out, you'll need 16 new ones. With any new lifter, visually inspect the bottoms to verify they're machined correctly and have a convex face (slightly domed). Try using heat on the spacer and lightly tap on it with a ball peen hammer to loosen it. Might also try taking those two collapsed lifters apart and see if they can be freed up to reuse.
I already have new lifters and cam, found a stock one. I also found the source of an issue, on the left is the old cam and on the right is the new one. Only two lobes were worn this much, I think this old cam is a goner.

I wonder if it’s just been worn down over time because all the bearings look exceptional for the age and all. There were no metal flakes or glitter anywhere.
This lobe also happened to be the area the ticking was coming from. It makes sense because the extra room.
now what to do with this old cam? Anyone have creative ideas, resale for decorating for some stay at home “antique” lady on eBay? Garage art idk?
