header gaskets, Aluminum, copper, or ball flange?

[xnoahx]

Whats the better gasket for the header collector? Aluminum or copper, summit sells both for the same price($10) and has about the same description for both. I was also checking out the new flowmaster header collector ball flange kit that replaces the old triangular 3 hole one with a two bolt ball falnge that is supposed to seal much better for around $45 through summit.

i dont know about the new ball flange, but i do know copper swells better under heat, and i love my header gaskits up top.

The rwo bolt ball flange is a much better design than the old 3 bolt design. Look at all you stock exhaust manifolds, they use the baal flange, along with all shorty headders. We do alot of Mustang exhausts at work and all the aftermarket companys use the ball flange with then and none leak and you can take them apart and not have to worry about gaskets.

Hey DesertDueler does anyone sell a ball flange that you can weld to an existing header? I am asking because I have a good set of headers I would love to retro fit to this style attaching my pipes. You must install exhaust systems.

no...no...no... you have it all wrong... they all blow out...

WELD THEM TOGETHER.......

Header straight to the pipes!!!

I havent had a problem yet...

when I entered a mudbog once with the aluimin gaskets they got so hot they melted and ran out like butter

Go with the copper if $$ is a concern. They are the only ones I've ever had any luck with.

I think im going to go for the ball flange collectors. Seems like the best way to get rid of leaks once and for all
