O2 sensors usually get damaged when you remove them plus any coating or oil that might be on the headers can burn off and destroy the O2 sensors. I would get some new Delco O2 sensors and some quality O2 extensions. I think one of the Corvette O2 sensors has a longer wire and will reach without an extension.
