Help locating gasket for header... (1 Viewer)

[jesus888]

So, I have a FJ40 with a crate 350 (from 1999) installed under the hood, and some what looks to be "block hugger" headers mated to a flowmaster setup...

I definitely have an exhaust leak on the drivers side, at the collector... but have NO IDEA where to get a new gasket for the collector... I don't know the company that made the headers, but I found a picture that is basically what I have... the key point is the 4 holes are NOT at the corners, they are in the center of the sides, just like in the picture...

Any idea where I can find the gaskets? Exhaust shop said they didn't know either

You know, I saw that, but I am looking for exactly what to look for so I can decide on gasket material too... everywhere I read on the Chevy forums says Copper is the way to go...

OK, I take that back... reading a little more about Remflex, and that just may be the ticket, thank you!

Perhaps, continue reading. Some people love them, others not so much..

However, it does not look like you have a ton of available options.

You might call Summitt Racing. They sell every header out there.

I would avoid 3-bolt header collector flanges if you can - the ball/socket type works a lot better and can take moving around a bit - as they all do eventually . Even with a braided stainless flex section the flat flanges will eventually leak....
