Scoring on the head of K301
 

I removed the head off of my Kohler K301, and I see some odd scoring above where the piston is. Here is the best picture I could get:

Attachment 5318

So my questions around that. First, what would cause that?? I don't think it is normal, is it? Second, is it repairable? Or does it even matter? Do I need to replace the head, or can I safely ignore it?

Its fine I have the same on mine just a little worse then yours mine was from a small screw that was sucked through the carb also have some scoring on my piston but it runs just fine I think you will be ok.

It does look like something was bouncing around in there a little.

As long as the gasket mating surface is ok and there are no cracks in the head you should be fine.

Be sure to sand the head good and flat using some wet & dry sandpaper on a piece of glass.
