The shells are fine and have loads of life left in them and rings for a standard engine are non-existent, so it's got everything else it could have had. It's a top end rebuild out of necessity, really - had new cam bearings, fast road cam, followers, springs, valve guides, stem seals, re-done the valve seats, skimmed the heads, new/ rebuilt pumps, recon distributor, leads, plugs, recon starter, rebuilt carb, flowed the inlet, steel timing gear, all core plugs, new spigot bearing and decent gaskets throughout so not quite just a strip, check and reassemble
