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!!.
