Kohler K301 cylinder head cracked?

After a thorough cleaning I was able to see the surface of the underside of my cylinder head. I saw what seemed to be cracks, but I’m not sure. What can I do to ensure these aren’t cracks?

Looks like a casting line to me. If you warm it with a small propane torch, often oil or fuel will sweat out of a crack on cast metals.

Ok I’ll check that out.

You need to get all that crud off the head and sand out that line.
Maybe even polish a bit.
All that roughness will build up w/more carbon deposits.
Kohler suggests removing the head and cleaning as part of their maintenance regimen.

The smoother and shinier the better!

Read into flattening the head. Though I prefer plate glass over tempered glass because it is flatter. Thicker the better.

That’s a good read. I don’t have any plate glass, just 1” think machined granite. It’s about 3 ft.² and came from my grandmothers house.

I bought a cheap piece of glass from Lowes to do mine. Worked like a charm.
