If anything I'd more trust the later #s since '85 was a "first year" engine.
My point exactly, bolts on a different angle, this IS a DIFFERENCE isnt it. ZERO difference would mean identical and i know for a fact as does Smacko that they are far from that.If they were the same cast parts which they are not,then every single attribute would also be identical,including fastening angles,cold start valves and coolant inlets/outlets. Angle changes in bolts will 9 times out of 10 mean they are differently torqued. So if it were me, id trust the 85 numbers, since thats the model he has.

Plus... he is looking for runner spec's. The angles that changed are the intake manifold bolts.
