The big 6 heads are amazingly interchangable thru 87-88 depending on exactly which one you have. Camshafts are another story however, BMP used to list an adapter for the distributor on the nose of the cam but it hasnt been in their catalog for a while now, don't know about other avilabilty. The intake runners are the ones that go between the plenum and the short 2-3" stub manifolds. My understanding is they improve torque a bit, but not horsepower, which is 169 on the 528i. Head gaskets can get weird when you put an early head on a big bore but they can work too.
