I got these heads for free on an engine a friend gave me. When I pulled it apart, it was evident water had been in a few cylinders for a while. I didn’t want to throw away the heads, so I had a local machine shop freshen them up. I didn’t notice this until they were all cleaned up. There’s some decent pitting on the heads from the aforementioned water.
Are these junk? These are the worst ones.
