[damage]

Yes Coon heads machined by Keith Craft and supplied as part of a full engine package that broke a timing chain and destroyed itself after 40 miles.

As per the other guys said the dye stains show the porosity and cracks in the darker areas.

I have a response from Keith Craft that says in essence (my words reading between their lines) yes we are aware they are crap but we sold them too you anyway.
