Also see Part Number 2036 for Big Block Round Port Weld Bead Header Applications. Remflex Exhaust Gaskets are soft and compressible so the suggested torque for each gasket, which is generally much lower than factory torque, is listed on the back of each package. Remflex is made in the USA so as to control every step of the manufacturing process guaranteeing a superior product that you can rely upon. Remflex's unique flexible graphite material has been proven for more than 30 years in industrial applications, where temperatures routinely exceed 2000 degrees-day after day, week after week, year after year. For over 10 years Remflex has been bringing this technology to automotive enthusiasts of all kinds to eliminate exhaust leaks for good. Experience has shown that no gasket "should" be reused if you want a reliable seal, therefore Remflex do not sell or market gaskets as reusable even though it have been told that they have been reused successfully in the past. Do not use sealants of any type with Remflex gaskets. The sealant burns out rapidly leaving a gap which creates an exhaust leak. Remflex Exhaust Gaskets are good to 3000 degrees which far exceeds the temperature rating of any sealant.

Torqued them as per the directions, and yes it took an arsenal of tools to torque every header bolt on a 396 in a 69 Camaro with factory air 🤣 zero leaks, will definitely buy this brand again.

Sealed the first time. Not sure about the torque ( kind of a joke) . Get them as tight as you can in the position you are in and the tool you are using. That's called torqued.

fit my 2" primaries Hedman headers and sealed them up perfectly. I'll never use another brand again.
