Gonna replace my header gaskets at the collectors.

Are the new copper or aluminum type as good as I hear?

Which is better, copper or aluminum?

I tryed the copper,& didnt like them(the ring seemed to distort the flanges when tightened up). I just have the Hooker gaskets now,but am thinking about trying aluminum......69 longhorn.

I have the aluminum ones on mine and will NEVER use anything else.
When I bought them, i had cheap nasty warped headers, they did the trick when the paper wouldn't. I have been running the same ones since '98, and have disconnected the headers countless times. I even put them on another set of headers all together. Still, no leaks.

My collector flanges already have the bent together problem from when the previous owner installed the headers then over tightened the collector flanges. Now they are leaking.
Can I beat the flanges back some and still use aluminum gaskets?
The aluminum appear to be more of a thick spacer, correct?

It is kind of a spacer, but more like a gasket. Picture the real thick gasket you always find under a stock quadrajet.

Thanks Andrew.

I'm goin up to "ach cough" summit this afternoon and get the aluminum collector gaskets. and put them in this afternoon.

Yup, that's how it normally goes. You got a d@mn good price there too.
You gotta figure if a cheap b@stard like me is using $25 collector gaskets, they must be worth it.
