I'm in the process or cleaning and rebuilding an LT1 for my 95 trans am. I started cleaning up the heads and noticed one spark plug hole was not like the other. It looks like a threaded insert, but i don't know if the head is salvageable.

Suggestions?

A helicoil done to spark plug hole should be fine. Is there something else wrong with the head?

Thanks for the response.

no other issue on either head, just the insert and the metal fraying on this one sparkplug port
