Very good pictures from both.
Picking up in mid assembly,and in general,I thought Flint assembled as such:..no?
..engine turned upright
..TDC determined,timing pointer
..cam lifters installed
..cylinder heads attached
..rocker arms,balls,studs
..intake manifold attached
..Valves adjusted
..rocker covers attached
..Misc. bkts. & switches
..build date/suffix code stamped
..water test w/Vac gauge
..oil cavity test
..block painted
..distributor attached
..coil & spark plug wires attached
..spark plugs inserted
..temp.switches applied
..hot test
..water & oil drained
..exhaust manifolds applied
..spark plug wire supports & heat shields applied
..component verification
..racked & ready for shipping

I thought Tonawanda did their assembly order differently.
Wasn't installing spark plugs,then painting the block afterwards one of them?
