What is suggested for Spark Plug gap for my 3L?

-3L bottom end/Heads
-SVT Cams/Injectors/LIM/UIM/TB/MAF

My plugs are Autolites: APP764

I searched but only found stuff on people running the 2.5 heads. (higher compression)

Stock plugs, stock gap- .052"-.056". Only way you need to mess with the plug type or gap (and some folks even question this) is with F/I. 3L hybrids usually run a one step colder plug (22 heat range) due to the high compression.

Stock replacement plugs at the stock gap. Only start lowering the heat range and gap when using forced induction of some sort like nitrous/supercharging.
