presuming hardware fits without modification then you can just have the ecm tuned to turn the afm off and any other needed fixes, company's like @BlackBearPerf offer this service.

Everything bolted right up including the harness only thing I had to re use from my 07 6.2 was the valley cover because the one that came on the 2011 had a electrical connector that my o7 harness didn’t have

The only real difference of concern is the cam specs between the non-AFM and AFM 6.2s. They're very close, and should be fine as both versions had VVT. It's the same as having an AFM-equipped engine and turning it off in the tune. It should be plug-and-play. I would've taken the opportunity to delete AFM while the engine was out.

Although, you MIGHT have an issue using the valley cover in place of the VLOM. Apparently, some engines with good or low oil pressure (I forget which affects it) can make the AFM lifters collapse and not pump up. To play it safe, I'd keep the AFM VLOM in place if the AFM lifters are in place. It doesn't need to be plugged in, just present for the oil circuit.


*EDIT*
I decided to look up the cams and other specs for the L92 and L94. Also, you'll need to retain your original injectors or entire intake manifold since your original L92 is not FlexFuel and the L94 you now have is. If you don't have to return your original engine with manifold, etc. as a core, you could probably sell that complete FlexFuel intake manifold pretty quickly as it'd be a complete "TBSS" upgrade for someone's Gen3 engine or even just the injectors as a "factory performance injector" upgrade.

Yeah, she's going to run rich with the larger injectors from the L94 and that could foul the cats. Easy solution is to swap over the injectors like Chris said.
