Exhaust Leak head to header

[Rwillia4]

peters- the problem on the early cars was a slip fit header to collector. My problem is on the other side engine to header.

jmimac- thanks from the web page it looks like they will do the job. Are they easy to port out to match the engine port?

Yes, they are actually somewhat fragile. They are many, paper thin layers of carbon held together with a resin. You can put them on the head with a few bolts and take a razor blade to notch them. Then take off and trim. Easy. Exhaust leaks really suck and these will absolutely fix the problem. You won't be disappointed.

Thanks for the link, jimimac351, these look just like what I need.

So, with these Remflex header gaskets, do you trim to fit the header or use them as is? They sell the one for my 428 FE (although I have Edelbrock heads), but my header ports are larger than the exhaust port on the head.

I saw that they will custom make a set for you and assume you just send them a template.

I have asked them for information on collector gaskets since I can't seem to get mine to seal no matter what I use. I have a collector that attaches to the header pipe flange just inside the body opening and then makes the bend to the "muffler". The 8 stainless bolts on mine loosen after a while too. My lockwashers lose tension and flatten and the stainless lock nuts I'm using have to be checked and tightened frequently. No flange gasket has lasted more than a month and I have to custom fit them from flat material. These things might be the solution, now if I can just get the bolts to stay tight!!.

They come ready to use just like a regular header gasket. Check the fit against the head and maybe trim a little, if necessary. It doesn't sound like you will need to.
