unless I'm loosing my mind... I just removed my factory original(never touched prior) exhaust manifolds out of my '84 in October and don't recall any square headed bolts. As stated above though there are a few possibilities such as pipe plugs where the A.I.R. tubes once were, or the inverted style which would only be in the passenger side head from the factory.
