I need a 3.5" donut gasket similar to the one below. Does anyone know a source for a gasket like this? I have found lots of smaller ones but none that are for 3.5" collectors.

I have got some 3.5" collector flanges on my edelbrock headers that I can't get to quit leaking. Any other ideas.

I had the same problem on my LT1 headers. I used a bunch of O2 safe Permatex on it, and that did the trick for me. I'm not sure where you could buy them at, just contact Edlebrock, they should have some or be able to point you in the right direction

cut the flanges off and use v-bands. they are considerably more expensive but they work.
