      I used copper on my Maverick for a while. Had one side I couldn’t keep a gasket sealed on, bought some layered aluminum Mr Gasket gaskets, actually split one and did both sides, never leaked again. I put the other one split on the Lincoln. I bought them at a swap meet, nos in the plastic, don’t know if they still make them or not.

      Those remflex are supposed to be good, too, but I’ve never used them.

        I've never tried those. Honestly, they seem pricey to me. I've had bad luck with about all of them, and good luck with about all of them as long as I could keep the bolts tight, the flange was flat, the gasket fit well, and the head was flat. Toss any one of those out, and none of them will stay sealed. My Hedman's wouldnt stay sealed for anything. But, it was hard to keep the bolts tight with as big as the primaries were. It was just hard to get to them in the car. With as open as your engine bay is, that shouldn't be an issue.

          I’ve heard some people are having good luck using high temp rtv silicon. I sealed the egr tube on my Vette with Ultra Copper Permatex, it never burned through, but it was probably 1” thick in a 1/2” tube.

            What I used to do to fight header leaks when I ran them, (and back then they were asbestos like materials) was:

            First, made sure the surfaces were straight, both head and header, and clean.
            Then I would install them and run the engine up to temperature, then shut it off and let it fully cool.
            Retighten the bolts, and some of them would even be finger loose.
            Drive the car for a few days, and tighten the bolts again, usually finding one that was loose.
            Then listen for leaks whenever I would drive and tighten them ASAP.

            It wasn’t perfect, and occasionally one side would need a new gasket, back then it came with the territory with headers. Some seal great, others seem cursed from new. I never had the expensive headers, though. Now I prefer cast manifolds feeling zero maintenance is better than the 15-30hp advantage of headers, but always messing with leaks.

              I had tried the RTV trick & it worked well for awhile. also when I install header gaskets I follow Steve`s routine.

              I was hoping others had experience with the REMFLEX before I spend over $40 for gaskets.....

                I brought this post back to life so I could give Remflex a review from experience.
                as stated in the original post a fellow rodder gave me the recommendation so I bought them. installed & torqued per their instructions on the 393 Cleveland.
                the passenger side header has been removed twice & re-installed on the same gasket. NO leaks at all & the driver side is good also
                I did not retorque the header bolts since installation & still holding up. so if you need header gaskets these are working perfectly for me......

                  I just redid the exhaust on the 66. I took it to an exhaust shop to finish the rear section that had fitment issues and needed welding. He did a great job, but mentioned to me that my passenger header was leaking. The MAC kit came with copper gaskets. I had never used copper before. He said he'd never had any luck with them and highly recommended Fel-pro for what it's worth. He does exhaust for a living, so there you go.
