The March Mini Mag issue? Just had a look through and can't see it

Lots of modern engines user alloy heads and/or blocks. Most of those don't have expansion issues.those heads look awesome! another company ( i think webcon? or something) makes alloy heads like this now, they dont have seperate ports tho not sure there used for racing becuse of the thermal properties of aluminium, the expansion when it gets hot may cause headgasket failure, correct me if im wrong here i cant think of any reason why else they wouldnt be used, the weight saving must be enormous.
