High temp gaskets?
So I've now burned through my 2nd set of gaskets in 6 months on the exhaust crossover pipe... time to find something better.
I knew that the material I bought (the highest temp stuff I found at Schucks) wasn't gonna last long, but I was hoping for more than a month.
Anyway... what should I be looking for? Something I can buy online? A preformed metal composite? The flange in question is just a standard 2 1/4" exhaust fitting.
Thanks for ideas and web links.

Mark, you might want to take a look at this as it relates to exhaust gaskets.

You might think about making your own gasket with some soft copper and a dremel tool.
Some good advice: Even the best wire-reinforced gasket will burn through if bolt torque loosens. You can tell a header or collector gasket is leaking by the carbon track on the gasket. Often, just retorquing the bolts will produce a leak-free seal.

Thanks for the responses guys...
Jamie; that's exactly what happened with the original gasket. Many moons ago I'd heard a ratttle under the truck, found it to be one of the bolts on the crossover and tighted it up. About 2 weeks later, the tell-tale "pfft-pfft-pfft" started. That was the first "edge burn".
Soft copper and the Dremel seems like the way to go... I'll check Summit, and I may just try some copper flashing from Home Depot... Hmmm...

fyi...
as a follow-up, I ended up getting gaskets from Summit Racing:
http://store.summitracing.com/defaul...237+4294921566
$4.88 each, free ground shipping but Summit's $8.95 handling charge sucked. They were still cheaper than I found elsewhere online, and I couldn't find anything reasonable locally.
