Rem Flex is going to make both the Head flange and Exhaust flange gasket based on a drawing that we're sending to them either tonight or tomorrow.(depends on when I get home) Once they get the 'OK' it will be 5 days to produce the first one to test fit and after that I'll have them available for sale. (I'm purchasing a good number of them to get it started)
Since a lot of people question my motives I didn't ask for exclusive rights to the gasket tooling and I changed the design to a more generic profile so anyone will be able to purchase a gasket from RemFlex to work with any ECOTEC engine once they are available.

These gaskets are 1/8” thick and compress 50% so this should take care of any leaks at both flanges. Also they rebound 30% so the chances of time causing a leak from movement will be unlikely. It’s not a group buy or one time deal they will be available as soon as the tooling is completed.

Just understand that even compressing down to .0625” will add a bit of space between the head and header. The same holds true for the exhaust gasket and it will have a 2.75” ID and no larger. The TOG header is a little more than 3.0” opening, but the exhaust pipe is only 2.5”. I needed to do this so there is enough material between the 2 flanges to be safe and guarantee a good seal. The combination of the 2 gaskets could possibly cause interference issues with the header and sway bar under certain conditions or other unknown fit problems, but for the most part it should work.
