Doing a HG job. My heads was sent to machine work, and arrived flat.
The issue is my block surface that after some cleaning with sckotch I saw the scratches that ptobably left from previouse HG job (not my fault), and the kind of slots around cylinder #1.
In addition I use metal ruler and filler gauge to measure flatness of the surface, and the passanger side is not as flat as the driver side. I can hardly push 0.15mm gauge between the cylinders.
I bought genuine HG set and head bolts.

Now, how to proceed?
Close it as is?
Sand it manually?
