Leaking header gakset - What gasket is the best?

[rlearp]

I'm on to round three of my header installation. I've got some OBX headers that I installed with the gaskets that came with the headers. Driver's side leaked within a few weeks.

I went back in and put a new Felpro exhaust gasket on the driver's side, and it too leaked within a few weeks (nuts probably backed out a bit and it blew out).

So, round three is the last time I want to do this. What brand of gasket do you guys suggest? And, if there crimp or locking nuts available, where is a good source?

Thanks,
Ron

on my cobra i had to use the oem steel gaskets...everything else burns up...i havent had any problems with bolts backing out, but did use longer bolts than what came headers...

they do make locking bolts for headers...some even keep oem studs in and just use nuts

Stock OEM Ford gaskets. I'm a fan of OEM studs and gaskets too

Stock gaskets will work perfextly even if used before,new they are expensive

i believe its Stage 8 that makes some pretty nice locking header bolts.
