Cracked guide boss in Aluminum head
I recently got my LS1 stocker heads back from machine shop and noticed that several of the valve guide bosses were cracked, where the new guides were installed. One is appx one inch down in the runner. My head guy, would rather not mention his name, informed me of this and said it was common. Has anyone ran into this? Is it a problem? Thanks for any info.
