Have you checked the header bolts, though?

They have a habit of backing out, even when torqued down, sometimes, after a few days.

I lost a few header gaskets that way.. bolts would back out a bit, flange would start to warp, gasket blew..

torque them, get it hot, let it cool, check it, wait a day or to and check one more time. that usally works

Might be a dumb question, but you did follow the torque pattern right?

Spend 30 bucks on copper gaskets once, and never look back.

I can tell when my header bolt start to back off from the sound. I just retighten them and it quiets down again.

I have also had good luck in the past using the copper type RTV.

I've always thrown the paper crap gasket they come with in the trash. I've had good luck with stock gaskets(name brand) and the 2 day check...............Karl

Snug them up by hand,
tighten them up a little following the correct pattern w/ratchet,
tighten them to spec w/torque wrench,
go for a twenty minute drive,
retighten w/torque wrench while engine is still hot,
They might back out some over the next couple days, just re-check them every other day or so until they no longer move.

on my CJ I would get cheap "MR Gasket" gaskets, the thicker paper type ones, them I would use 2 on each side. It's the ONLY way I can get more than a thousand miles out of them. Torque, run engine, re-torque.

btw my hedders were cheap so they would warp more than a good set I bet.

I guess there is a couple way of doing this. the best is to install the header then run it till its in the shape its in now. then remove it and have it ground flat, then reinstall without a gasket and it will be fine. if you have an alluminum head then you are forced to run a gasket as a insulator. good luck

ps, do not run silcone sealant if you are using an O2 sensor, it coat the ellement and junk it out.
