HedmanHedders Exhaust Header/Manifold Gasket, Round Port, compatible with Small Block Chevy, Pair

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.

PERFECT FIT ON TIME DELIVERY INSTALLED WITH EASE HOLES PERFECTLY CENTERED..I HIGHLY RECOMMEND THESE TO ANYBODY WHO IS INSTALLING HEADMAN HEADERS.

Fit perfectly and worked as described

Great drop in replacement

Dose not look like. The pic and dose not fit a amc 304

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.

Good gaskets but needs better packaging. Arrived bent up.

Good quality 👌
