IMO steel gaskets should only be used surfaces which you know to be machined true. FPP-1406 are excellent gaskets for the price and can usually be found at about any parts store. I've never had one blow out.

I've heard really good things about the Percy's aluminum crush gaskets. They seem to seal the best and won't blow out like typical copper gaskets.

The Percys are really thin, and are hard to get in between the header and the block without bending or crushing them...other than that, they do seal pretty well and are guaranteed not to blow out, but after spending 50 dollars on header gaskets, I would hope the same thing.
