You should watch videos on how hard head gaskets are to design if you want an idea of some of the engineering involved- I think "engineering explained" did one recently on youtube.
What I’m saying is, should we still be building engines that rely on “the” head gasket to keep fluids separate?
An engine cylinder at a minimum must deal with: lubrication, fuel, and gasses. The exhaust manifold deals with half of the gases. I can’t recall if common rail injectors are still technically part of the head (I can find pictures where the CRI system sits on the head, with separate gaskets, but I’m not a mechanic).
With modern manufacturing would we not be better off splitting these tasks up so that only a cracked engine block can mix fluids. Not a torn gasket, not a warped head, not a thrown rod (though rods are going away too).
