Didn't want to make the short trip to Oklahoma huh?
An engine that old should need new cam, lifters and springs.
Routine items: Rings, bearings, gaskets, oil pump, timing set, valve job
Do not know items: bore size (new pistons), crank size (grind), valves, valves guides, rockers, pushrods,
Machine work: cam bearings, hot tank, freeze plugs, deck block or heads, resize rods, aline hone.
No way to tell until you get it apart.
Do not cut any corners, not worth it.
