How deep is the induction hardening on magnum heads - can I do a valve job?

I don't disagree with the "fix it right" part, why do you think I asked how deep the induction hardening goes??!! if it goes a hundred thou deep, I'm not throwing my $$$ away by installing seats! If you KNOW the answer to my original question, please state so. But you didn't even attempt to answer it.

Your question has been answered already, did you miss it? Induction hardening goes .060" deep if you're REAL LUCKY. Usually only on the order of .010-.020.

There's no concrete answer, as each head is a little different in consistency.
