Anyone tried XS Power headers?

I've had a set of Hooker Super Comps on my car for for 5 years and 2 engines and have not had any header to head leaks yet. I'ts REALLY nice not to hear the tick,tick,tick!! The only thing Ive done is to double gasket the headers and cut the flang between each port. The cutting of the flane is controversial...but it's worked for me.
