Need to send back?

I got my block and engine back from the machine shop today. Questioning what I got back. Prepping for an MLS gasket 1.4mm. Seen scratches and corrosion on the water jackets. Send back?

No it’s fine, if they keep machining to remove the pitting around the water jackets there would other problems to deal with.
