Used these after installing longtube headers on my Suburban. Installed these March of 2023 and still have had no issues with leaks! The long tube headers came with a gasket that was not good quality at all but installed them anyways and after a couple hundred miles they formed a leak towards rear exhaust ports.After researching the best exhaust manifold/headers gaskets copper is one of the best gaskets to use due to being able to conform to the surface creating a tighter seal especially with headers and their high heat they can create. Also copper gaskets are generally reusable so that makes it better if I ever needed to remove the headers to do spark plugs in the future, although I don't need to remove them.Would purchase these over and over again!

They've been installed for a few months now on a daily and have been working great.
