Those Remflex gaskets sound like the way to go. When I got this car the guy used to race it and had longer than usual style headers on it. I'm trying to keep those going and they are vintage but sound great. I probably need the extra thickness and sponginess of these gaskets even though the headers are in pretty good shape. They appear to be a little more expensive but it would be worth it if I didn't have to take these headers off again for awhile.
