Send the LS2 to Texas Speed and they can install Darton sleeves and make you pretty much any size engine you might want

I’m having LME put together a 440, went with the Frankenstein F710 heads. Might want to look at those.

F710 heads were not around in 2011

The heads require a specific intake manifold and a unique header. They are not like a typical LS engine in that regard. Also require a specific shaft rocker setup. Combustion chambers are 50cc, which is very small...great for high compression. Not pump gas numbers, unless your going with a dish piston. Intake ports are 313cc, which are huge. Would be lazy on a street engine. The DR heads are designed to be a drag race only (hence the DR designation) cylinder head, that live up above 7k rpm. They are very capable of making incredible power in a high rpm setup.
Having said all of that, I wouldn’t consider running a set on the street.
