I owned 2 240K GL 2 doors. The earlier one had quite differant inlet & exhaust manifolds, but the differance seemed due to adaption of antipolution gear. On the later one, there was a "heat stove", and a flap arrangement to divert exhaust gas to the base of the inlet manifold & heat it during startup. The two manifolds were bolted together. The earlier engine had seperate manifolds. Looking at the two I suspect that the earlier one would perform better, the exhaust manifold had straighter better looking path, and there was a little less complicated crap involved. IIRC the later car also had EGR, while the early one did not.
