Car didn’t pass inspection because of an exhaust leak.
So... Just ordered some manifold gaskets from Pelican Parts. Question is. Is this copper soft out of the box, or does it need to be annealed before install? Thanks for sharing your experiences. |

I've never had to do any prep to the gaskets. Just put them in. Check the head surface to make sure its clean doesn't have any erosion, and you can run a flat file over the ends of the exhaust to make sure they're flat before bolting them up.
