About this item

  • 1-1/8 inch width x 1-1/2" height Stock Square Port; Ford V8 - 302 ('81-'95), 351 ('69-'97) Windsor, 1-1/8" x 1-1/2" Square Port, Manifold or Headers, 2/Set
  • Heating and cooling of the exhaust system causes header and manifold flanges to warp resulting in gaps between the head and header which Remflex exhaust gaskets seal completely due to the thickness and compressibility of the 100 percent flexible graphite
  • Remflex exhaust gaskets come in a standard 1/8 inch thickness and are designed to crush 50 percent allowing them to fill any pits or gaps in the flange surface up to 1/16 inch
  • The aluminum cylinder head and steel header or manifold combination are configurations that readily cause gap issues in the mating flanges due to contraction and expansion of the dissimilar materials; Remflex exhaust gaskets fill those gaps permanently
  • There are no rubber binders or composite materials in Remflex exhaust gaskets so they will not shrink or harden due to time or temperature eliminating the need to go back and continually retighten your flange bolts


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 have 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 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.

You have to be extremely careful with this material, it is fragile, delicate. Do not drop it or bend it. You only get one short getting it installed correctly. Works well if you don’t mangle it.

I love this gasket. Used this set to seal BBK long tube headers to 351 Windsor.

I had a nasty leak. Took everything apart. Put these in, bolted it up and what’s that? Idk.. I can’t hear a leak anymore! Best gaskets I have EVER used!!

These things sealed perfectly on the first try...and on really tricky headers. The car is a '72 Pinto with a 302 sbf and I'm running Hooker swap headers....which have a 3 piece flange. Primaries 1&2 are on the same flange, #3 is it's own flange, and #4 is also its own....so you can see how that might get tricky. No problem at all, however, much to my surprise and delight. I had been using the brilliant (and now discontinued) Earl's Pressure Master gaskets with replaceable seals....but these have proven a more than adequate substitute.

Very nice feel. Installs nicely, very satisfying crush as you torque it to specification. I have not run the engine yet, so can't speak to the longevity.

So far so good. They installed very easy and seem to be of good quality. They sealed up the leak I had. These gaskets are pretty thick but they compress alot so I imagine they would be good for anyone who has aftermarket headers where perfect fitment may be an issue. Very happy so far

1995 ford f150 lightning... 351 Windsor motor... tried other gasket, leaked, well actually blew out, but the Remflex sealed me up perfect... good product. -you can really torque 'em down, but you don't have to... my header bolts were hard to get to, and couldn't get much torque on them, but sealed up anyway. They are pretty thick, like 1/8", but squash down if you torque them for a great seal. Pure Graphite and made in the USA, a little pricey, but this is the gasket you want to use!
