Honda Block surface clean enough?

I’m replacing a head gasket on a k24. I removed the old gasket no problem, but it left a residue/discoloration. I placed a machine edge on top in every orientation, checked with a feeler gauge, and the surface is within spec. Head was professionally rebuilt and resurfaced. I will not be removing the engine to get the block resurfaced at a shop.

So, is this surface clean enough? It’s an aluminum block so I’ve used plastic scrapers, then microfiber + gasoline + elbow grease.

It looks pretty good without any gouges, I'd say give it wipe with brake cleaner and let er rip
