They will all last for years. If you find yourself going through valves like crazy, the seats probably need to be replaced or recut.

Yeah, probably some of that same bad batch of Kibblewhites that ended up on EBay.

Ferrea is the best there is, and the price isn't out of range of the others. I won't even use Kibblewhite anymore. They don't hold up, especially in an aggressive build. The more aggressive the cams, the faster the intakes cup. I have had Kibblewhites fail before burning 5 gallons of gas. Put Ferrea in the same build, with identical seat profile, and raced it 3 years, never even changing a shim. Wiseco is probably good as well. I just don't have enough experience with them to say good or bad. If Ferrea isn't available, I usually go for Wiseco or Xceldyne.

I hope the Wiesco hold up as I don't feel like tearing it back apart any time soon, Ferrea were hard to find a couple months back everyone was sold out, even Wiesco was back ordered.
