This started off as a big7, now it’s a Chromidium nippy block.Different kettle of fish altogether and much easier to deal with as you can take the block off and send it to one of a number of well qualified enginers on this forum.
I certaily woul not be having seat insrts put in this block as it leaves very little margin and if Chromidium is even rarer than a Nippy engine.
Top skim to narrow the seats a bit, and very light recut.Slightly larger valves are preferable to seat inserts.
You don’t need hardened seats for unleaded, it’ a fallicy.
I probably wouln’t use this engine without a Phoenix crank for fear of something going wrong.
