The LBZ with the six speed allison are a great truck, my brothers got one and he loves it. The late lly's and all lbz don't have an overheating issue that I'm aware of, some of the others may know more. Both are a good starting point though. There is little difference between a GM and a Chevy, mostly aesthetics.
As for the EGR, a blocker plate is installed in between the egr and the intake, and you will need a EGR code blocker which are pretty cheap.

I sure do

No overheating issues with 06 and up lly-lbz engines, the 06 lly-lbz are virtually identical, the lly is just tuned for 310hp and the lbz is tuned for 360hp
the LBZ/LMM pistons are known to crack under extreme timing and fueling, if you keep your tuning conservative you will not have a problem

the 04.5-05 LLY is very well known for its overheating issues, and if i were going to be buying a duramax i would avoid the LLY, i would pick an LB7 or LBZ, or maybe an LMM

LB7's have issues with injectors, but gm has a injector warranty of 7years or 200,000miles, so if i were going to buy a n LB7 i would but an 04 with low miles, so your covered for as long as possible
You can buy a EGR block off plate and EGR code eliminator "fingerstick" from Kennedy diesel, just search it on google:

I think the '06 & up LBZ or LMM is the ticket. You get the best engine power & tranny combo.

There's no difference except styling between GMC/Chevy. They come down the same assembly lines.

I wouldn't walk from the earlier ones, but 360-365 and a six speed with manual shift ability is better than 310 and a 5 speed without.

They are both great with pluses and minuses.

The LLY can use DSP5 switch on the fly tuning,

The LBZ cant but has a stronger 6 speed trans.

Stock vs stock LBZ IS better.

But MOdded they both can be equal

if you want big mods, save your money and buy an older truck, then you can build the trans/converter and throw a big EFI tune in it and have a bad hot rod.

Its up to you. Any truck you buy reguardless of make or year has issues to be upgraded to make them faster and more powerful, its up to your wallet!
