The flanges are not one whole piece on each side, meaning they are seperate for each primary tube. I'll add a pic for reference. Do y'all know if this will affect the seal? I have never seen this and I wanted to know if they will leak or not. Thanks!

A lot of guys with chronic leaks end up cutting the flanges between #1 and #3, #5 and #7, #2 and #4 and #6 and #8 anyway. Some say it helps minimize leaks if the flange is somewhat warped. Should be fine if the flanges are thick enough. 1969 Dodge Coronet Super Bee 383 A4 1970 Plymouth Road Runner 440 FC7 (sold)

I believe a long connected flange warps and pulls the tubes away from the head. I've seen it enough times that I started separating my flanges 20 years ago or so. Less weight, cleaner appearance, better plug acess & visibility are other advantages. I'd say headers with connected flanges are made that way for ease of production due to less set-up time.

Only piece of advice I can give is don't skimp out, buy the remflex gaskets. I found on my used set the sealing flange was a little concave between the middle cylinders so I cleaned them up a bit with a file.

I do the same and for the same reasons, cut a brand new set for the GTX

Which ones have y'all had the best luck with?

I started out with thich Mr. Gasket paper gaskets, then I moved up to copper gaskets and finally up to the Remflex...unreal. The Remflex gaskets could probably seal just about any issue you may have. They were a little tough to get started due to their thickness, but once you get the bolts started, they are crazy good and WELL worth the money.
