X-heads enough for 408 stroker?

I'm currently going through the same choices right now for my 408 build. I have some X heads on my running 340 right now (condition unknown). I also have some heads that came off of a 360/300 hp crate motor (need to be redone). I bought a pair of Edelbrock's, but sold them last winter to rebuild my motorcycle. I've looked at RHS Indy heads, and now the Airwolf heads also look promising. So many choices...
