In my opinion, Supertech will be more than adequate for your power goals. Personally, I'd stick with OEM sized valves (the only reason you're replacing them is because you burned an exhaust valve iirc?) Are you going to replace the factory valve guides as well?

Is Ferrera stuff worth the upgrade? I can get all supertech stuff for a full rebuild for relatively cheap.
Can any machine shop upgrade the head to accept oversized valve stems?
I want to overbuild for my goals. I'd rather take the steps now to avoid a potential problem.
im at 706 with stock valves everything else ferrea and fbm studs boost 3k miles so far no issues except when i popped a freeze out plug
