What's different about LSA covers? Bigger breather holes?

Right now i'm having oil consumption issues, running the Gen 4 6.0 covers.

The LSA valve covers have improved oil splash guards, revised breather system in the valve covers. I plan to switch to the LSA covers, LSA PCV tube system, to a catch can, then back to the intake.

I haven't driven the truck since taking it home after doing the clutch on Saturday. No intentions to, until I get all of the components in to do the ZL1 breather system.

Same wimpy 10mm breather lines though? My 454 had just the one small breather, even the 350 got a 3/4" breather line. I added a 3/4" breather line to both my 454 and 350 LT1 on my non-boosted Camaro and oil consumption plummeted. Those were both baffled, but my point here is that I wouldn't hesitate to drill out a valve cover for a bigger fitting, especially that newer one with improved baffling that would carry away more air and less oil.
