What brand of gasket should I use for intake/exhaust

I've used the remflex carbon gasket and standard felpro...if the manifold surface isn't true enough for the felpro the remflex may help but only for a short time.

Have the mating surfaces milled or sanded or something to get them flat or even the thick gasket will blow out.
I did something like 3 gaskets in the first 2 years of owning it. Started leaking a couple of months after each time...until I fixed the manifold surfaces.
