So, finally had a chance to talk to machine shop: Cylinder bores are marginal - good at bottom, .0045" to .005" at top. Would probably work fine staying with CI pistons, but I decided to have the cylinders bored and go with aluminum pistons, new rings. I am going to stay with babbit rods as all rods still had two shims under the caps so I should be able to get a good fit on the crank.
What I am doing: Deck block to clean it up. Mill head to clean it up. Hardened valve seats. New valve seals. New camshaft bearings. New crank bearings. New aluminum pistons/rings. Staying with original camshaft/lifters.
