Cylinder head problem

[DSMdarrell]

Alright so I got bored and got my dremel out and was cleaning up my head a little bit. Not porting it or anything I was just using this buffer attachment that was made with like a softer red scotch bright material. Something I thought for sure wouldn't remove any metal, just something to clean it up so I could see the condition of the valve seats. Check out the attached pictures of the valve bowls directly under the seats and you'll see what I'm worried about. There's a good amount of metal removed in one of them. I don't think I did it I don't know how I would of. Like I said I was just using a soft buffer type attachment to remove carbon. I even purposely hit the metal with the shaft portion of the attachment to see if it would mark it up and it wouldn't. I did the same with the chuck of the dremel. Couldn't replicate the condition to save my life. Which leads me to believe it was done by someone else and I just cleaned it up and made it easy to see. All opinions wanted/needed thank you

Please help I need to know if this head is junk or not

I assume you mean the machined portions just inside the port from the valve seat? If so it's fine, that's where the valve seat is blended into the port throat.

Yeah I got to say, I don't see any anomalies!
However the Head surface has light superficial damage.

What exactly is the problem?

I was worried about the areas right below the valve seats. It seems like they all have different Amounts of metal shaved off. Like the first picture has a huge amount. Compared to a couple other ports having barely any

Those areas have very little to do with anything.
Head is fine .
