2008 LT confusion

I've been doing some research for small tuning projects on a 2008 Cobalt LT. It has an automatic, with the (uh) "upgraded" 2007+ version of the L61, 2.2 engine. There's two things in particular that have been urking me:

1.) 2.4 Throttle Body swap: Everywhere I go on the internet, people claim that a 2.4 throttle body swap (and this would probably be with aftermarket intake manifold and exhaust system) should and can only be done on an LS model Cobalt. At first I thought it had something to do with confusion between the ECU and automatic transmission, but I saw a video that someone has done it to an automatic LS.

So firstly, if I may kindly ask, if and why a 2.4 throttle body on a 2.2 LT would be an issue, if you had it tuned to handle it.

2.) Updated L61 Camshaft swaps:
Although it is the same engine, I kind of spite the fact that the 2007+ 2.2 was still called the L61, because it made this extremely frustrating to research. The 07+ uses a weird timing system, and so far I have not found a solid manufacturer that develops performance camshafts for this generation engine. I found this COMP cams that are (according to the notes) unequal length, and was wondering if this compensates for the timing mechanism, but the application says L61 05-09, so I'm not sure if they have the application info correct.

However, I just wanted to double check and see if anybody knows of any others.

I like my current Cobalt and would like to resist the urge to get a different one just for some tuning fun. Thanks in advance :)

The 2007+ L61 still runs standard timing IIRC. They didn't put VVT into the 2.2L motors until 2009 with the LAP. So you should be able to run any standard Ecotec 2.xL cam.
