Like Gary, I've never had a problem with Felpro's. I've got a set on my F250 with a 7.3 IDI, reused head bolts (not studs), no sealer on the gaskets (like Hylomar), and have a boosted over 15 psi on several occations without a failure. So, in my experience, they've worked well.
But, I too have read that VR are good as well. In fact, I just put a set of Victor Reinz head gaskets on my 6.9 (with studs, and Hylomar on both surfaces) just give them a try as well.
