I agree with Mike. Those combustion chambers look fine, and there is no reason to send it back or complain about the head. I knew a guy who polished his heads and piston tops to a mirror finish on an Olds V8. When he honed the cylinders to install new rings, he didn't get the honing grit cleaned out very well, so he had worn rings in one week. He took the engine apart, and the heads and piston tops had the same coating of carbon, just as they would if he never polished them. Also, polished isn't always the best for flow.

I bought a Snyder's 5.5 head years ago, and it's still in the box. Just for kicks I'll have to check it for flatness, and see how the combustion chambers look.
