I thought I could get a good argument started on the subject of head gaskets. AH Spares recently announced that they are offering multi-layered all steel head gaskets for Healeys. Suitable for both competition & street engines and aluminum heads to cast iron or aluminum blocks. Presumably, also cast iron heads, but the ad did not state that.
I know they are not alone in offering improved head gaskets.
Being a cynic, I have to wonder if steel gaskets are really better that copper gaskets or are they just cheaper to manufacture? 
Being an engineer, I have to wonder if a steel gasket is really a good choice for an aluminum head, especially in the sealing ring area around the cylinders?
