They chased that around and I think the problem was mostly tamed by coolant changes. It was common way back when for aluminum heads on iron engines to have "issues". I guess the gaskets are still around for the alum six, or so it seems. I still think the little edge of copper peaking out between the iron head and aluminum block would look cool! especially with the fluids seeping as they are want to do with copper gaskets :) Mark Price Morgantown, WV 26508 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrac II "I realize that death is inevitable.

Three different metals all tightly bolted together, would there be a chance for galvanic corrosion or dissimilar metals corrosion? Gee it almost sounds like it could become a battery????? I know, that won't happen. Come to think of it........ How is that problem dealt with on current engines, aluminum head on a cast iron block, or for that matter aluminum radiator with cast iron engine, is something sort of sacrificial on these designs?
