I have no trouble with those perforated metal composite type that they supply in the gasket kits. I put high temp silicone (smear) both sides, nip em up most of the way, let it set and fully tighten. Check when cold 3 or 4 times and then occasionally. Keep em tight.
But the MOST IMPORTANT thing, make sure the flange on the header is STRAIGHT!!! Mine had a .100" bow in the middle, no way I could get em to seal. So I filled it up with weld, the ground it, belt sanded it, check with straight edge until it was straight. .....No leaks now!

I feel that so long as your surfaces are straight, pretty much any type gasket would do the job. Keep a check on the bolts....
