Maybe they were trying to lower the compression, you'd think the head would be a little more washed.
Or maybe it was leaking coolant before for the the prior owner. Then the prior added an additional head gasket to seal it enough to sell it to PrehistoricPredator.
If the mating services aren't perfectly flat, they might have tried to seal it up like that. Not the proper way, but it's a quick fix to sell.

I need to move a dowel they have two in between the valve cover and head. I want to move one to the cylinder and head. Per the manual shows. How do I remove one? I’m guessing this will help keep the head gasket in place

Are you looking to remove the dowel? If so, find a drill bit that fits the inner diameter of the dowels snuggly. Then take a pliers and carefully remove it. The drill bit makes it so you don't crush the dowel. Make sure you use the smooth end that goes into the drill chuck, not the drill bit itself if that makes sense.

There are a bunch of different ways to do it. Just check youtube.

Can I add yamabond to both sides of the head gasket and valve cover gasket. Light layer both sides?
Is this the niche cylinder that came with the bike? You're getting an oem cylinder, right?
Yes it is. Can’t afford a new cylinder at the moment

Major oof, not a good idea at all to run the niche. You'll end up spending significantly more in the long run, with an uncomfortable chance of a catastrophic failure causing significant lower end damage. Then you'll be spending thousands rebuilding the top and bottom end, trying to find case halves etc. We'd all hate to see all the work you're putting in go to waste because you didn't want to spend a couple hundred on a proper OEM cylinder.
