I think you're correct there. It would be impossible for it to go out the exhaust in one piece. I've just said in another thread that I have never installed hardened valve seats and don't think I ever will. This is one reason why. IMO, you won't be able to put another seat in those recesses, they will have to be machined even larger, leaving even less of the good original cast iron (another reason I don't do it) and I'm not even sure suitable new seats are available. I hope you don't have to rebuild a different block.
Please keep us informed on how you go with it.
