Intake manifold question

[mudman]

I just want to make sure that any regular EA71 manifold will fit on any other EA71 engine. I'm pretty sure that my engine is early eighties (80 to 82). It is not the wide body style.

 

Will any EA71 manifold from the 70's through the early 80's fit? I'm not worried about carb style, because I'm trying to retrofit the intake with a '66 chevy 2 bbl, and I want a barrel for each side of the engine, so I'll be doing some chopping and welding, and destroying good pieces. Just want to know which intake to purchase at the junk yard.
