How clean does the block need to be?

Doing head gaskets on a NA ej22, sent my heads off to the machine shop, so I know those are good. I need to know how clean the block needs to be before I reinstall the new gaskets and heads. Everything feels smooth, but there is alot of discoloration. I don't want to go through all this trouble just to not have a good seal. I have spent a couple hours gently scraping everything with a long razor blade being careful not to nick anything. Im just a little uneasy about the discoloration where the old gaskets used to be. Any help is greatly appreciated.

The discoloration is normal. What I'd suggest checking for is the straightness of the deck. Also check that there are no dings/scratches where the cylinders seal.
