If you have had 2 diff gaskets and it is still leaking the flange on the header or manifolds is warped. OEM MLS ones are the best.

I ordered my gaskets off rockauto. VICTOR REINZ Part # MS16124, they are identical to factory GM gaskets, but less than 9 bucks a set.

The OEM steel gasket, re-used it 4 times. I just threw the one that came with ARH.

yeah my pacesetters came with some leathery-rubbery feeling gaskets and i just trashed them.. Something else to look into is header sealant.. it's like a puddy but dries hard.. i used alittle on my header installation 3 years ago and still no leaks.. I would look into it since your having such a problem with them sealing.

Put a straight edge on your flanges. . . .

I could tell by eyeballing it and had my dad look too didn't have a straight edge but you could see it waive little bit

Stock gaskets are the best.I always reused mine from the exhaust manifolds for the headers sealed perfect.I don't get why all these header company give you the crappy felt ones with there $1000 header systems.
