You certainly CAN reduce detonation with coolant temperature. An engine at 190 degrees is much more detonation prone than one running at 160. It IS as simple as that.
LMAO, what a revelation! So temperature does matter but the ability to shed that temperature into the cooling system doesn't.
Obviously my response was not to say engine temperature has no difference, it means it has no difference when all things kept equal besides cylinder head material.
I feel like I'm talking to Joe Dirts Dad. "how does it work? It just does!" Or in the case, "it just can't!"
