I doubt that you will need any shim, but I'm not 100% familiar with the l20b per-se, only vicariously and limited at that. There is certain amounts of valve to piston clearance that you need, that's all I know.
The swirl marks on the intake manifold gasket surface are not bad, as long as the surface is true; that is what matters.
You can just vacuum those shavings out. For cleaning the head surface, stuff rags down the cylinders.
What did you mean by debris in the #1 cylinder? Just carbon? Yes, just clean it out. If there are any chunks of carbon buildup on the combustion chamber or piston tops, I would get most of it off. You seem to understand that stuff isn't supposed to be all gouged and s***, so I think you can handle any cleaning.
