7a valves on turbo head?

I've got a 7a head I converted to 3b, and am now going to have new guides installed. I'm probably going to end up buying new Supertech or Ferrea valves for it, but before I do I thought id check if it was crazy to reuse the stock valves from the supposedly low mileage 7a head? I weighed them as per this s2 forum post and they're are indeed non-sodium filled.. Will likely go with HD springs and lightweight retainers, to future proof the head.. so guessing new valves are probably smart, but thought id check thoughts here.. It will eventually be on a ~350+hp build but will remain mostly stock for now

Also, if buying new, anyone have opinions on Ferrea 6000's? have mostly read good things on them, but supertech seems more often used

Thanks :beer:

No reason you couldn't, but likely more reasons you shouldn't. Mostly down to being cheap insurance. Pretty sure it's $200 or so for some Ferrea exhaust valves. That's a fair cost for price of mind.
