Copper header gaskets leaking like a civ
i bought some copper header gaskets because i got tired of blowing thru my carbon ones. well they barely leak when running temperature but man do they leak when cold. anybody else had this problem and or a solution? did i supposed to coat these with any sealer? i have been thinking about just biting the bullet and getting some aluminum ones since the will conform to any irregularaties on the flange.

If you are talking about where the header flange seats to the head, it is hard to beat the factory MLS manifold gaskets. If you are talking about the collectors, invest in v-bands, and you will solve your problem. Just don't warp them when welding them on.

oh i should had said the header flange where it meets the head was what i was referring to. So if i use no gasket will it scar the head up. Also if i use some high temp rtv will it need a full 24 hours to cure? i am now interested in going this route.I have some old headers that i had fabricated and i think the flanges are a little warped. Would going no gaskets cure this?

I like the Earl's Master Seal header gaskets with the thick graphite cores (replaceable) in an aluminum frame. I haven't blown through one yet, and they don't need constant re-tightening.
