Dis-similar metals, aka steel & aluminum, don't generally mix well. Not sure the technical term but over time the steel sort of eats into the aluminum head surface. Also the steel gasket is a harder material than the aluminum head which means the gasket could imprint itself into the head.

Doesn't seem worth the risk with high dollar heads.




BUT BUT BUT ....

People run MLS Cometic gaskets with alum heads ??????

The fire ring , if that is what it is called , on a felpro gasket is STEEL ????

Coat the gasket with copper spray and he should be fine ...
