Default AFR head damage

Friend of mine has a c5z with afr 205s under a 3.3 whipple.
The blower came apart after it ate some dirt/dust and we decided to check the heads and cylinder walls before putting the new blower on.
The heads definitely have some damage and I'm wondering if they can be repaired or if they should just be replaced.
The cylinder wall also has a small amount of scoring, I'm pretty sure it's no good but I thought I'd post some pictures and see what you guys think.

The missing material between the valves is common. Honestly, every set of used AFR heads for sale on here look like that.

Would the seats need be cut out, hole welded and ground down, and then a new valve job?

The scratches on the very top of the cylinder wall will barely catch a nail, my thought was if you can feel them they're too deep

Think I'll be selling these heads and going with a bigger set for a 4.005 inch bore.
Any idea what they're worth with the damage there?

What I would do is have a machine shop check them over and pressure test them. They may be good to go. Lots of guys on here have had heads that look like that get the okay from the machine shop and then they run them with no issues.
