How do I handle scarring on a cylinder head?

Question

A few weeks ago, my Rebel 250 blew a piston, allowing the piston rod to beat on the top of the cylinder and the valves.

There's some scarring there now, as well as a jagged protrusion or two. What are my options for repairing this scarring?

Can I hone it down to simply get rid of the jagged bits, then brush it out?

Or should I replace the entire cylinder head?

Here's an image of what I'm working with. It's not great, but the damaged head is on the top.

Answer 1

Depending on the depth of the scar, honing might work. Otherwise, depending on availability of parts, you can replace the cylinder head.

Answer 2

If the damage is mostly superficial, and it's not warped or causing a gasket leak or a valve leak ( which could let coolant into your oil and then you will have problems), I think that you could very easily get by without replacing the cylinder head.
