These gaskets came with my new headman headers when I purchased them. They sealed up and worked great. They worked so well that when I had to remove one of my headers to make my transmission install easier I could’ve easily just re-used the old gasket. But for the price it’s better to be safe and always just pu in new gaskets!

I originally used aluminum gaskets when installing my headers and they leaked like crazy. I had to remove them and replace with these to stop the leaks.

Perfect fit, great quality. Easy to install. You can leave on the first and last bolt in, and slide the gasket in place. This is on a small block 350 with headers.

Used these on my 350 sbc. My heads are square port whereas these are round port header gaskets. They sealed up my headers perfectly though. I’ve heard that people with square port headers actually have better luck using the round port gaskets. So far so good. The diameter of the gaskets port is slightly larger than the largest width of the square port (i.e. none of the gasket covers the exhaust port. But even if it did, I don’t believe that would be an issue because that particular part of the gasket would just get burnt up and spit out).

They fit my headers perfect and fixed my pesky exhaust leak problem. Also, easy to install because of the design- you don't have to completely remove the headers, just loosen them a little and drop them in and they hang perfectly positioned on the first and last bolt.
