6.2 Replacement Motor Options

[Gocats96]

I have another recent topic on whether to replace lifters and cam, or do a motor swap after the L5 lifter failed and shredded the cam lobe. 

Sounds like I will be replacing the motor. 
 

With this in mind, are there other variations apart from the standard 6.2 that came in my 2019 Silverado? I see several variations on the Chevy website, but I am unsure on what will fit and what will not. 
 

It must be a direct fit or as close to it as possible or I doubt the mechanic would consider swapping.
