a cam kit like the piper 285T or the kent cvh34,
new piston rings,gasket set, water pump,oil pump,vernier pulley, cam belt,
heavy duty bearing shells, conrod bolts,flywheel bolts,and some more and maybe new pistons, rockers , valves and valveseats.
I guess the crankshaft needs to be machined at that amount of mileage.
u also need to have the cilinders getting honed and maybe rebored.
not to forget the 'special' tools and other bits.

its not possible to say what needs to be done to any particular engine. its best to get hold of some education like 'rebuilding ford's cvh engine' from Haynes.. hope this helps
