M64 (factory 3.6) ran 11.3 (not 10.4) with twin plugs, BUT also had knock sensors and smart engine managment, that probably would retard the ignition if knock was detected (this is how it's usually done, but I don't know the engine managment well enough to state with 100% confidence)
what are your pistons?
