with the minimum mods that you have there's no reason to put any larger size injector into your car.
If you do put larger injectors in, because you think "bigger is always better", you'll have to get your car re-tuned to match up to the new injector size.
You will gain NOTHING by putting a different size injector than OEM in your car.

The o-rings and plastic caps, along w/ the inlet filter baskets, all get replaced with new pieces.

I agree--- NO NEW INJECTORS !! If you have 28#'s already and without hds/cam you are just asking for throuble--- injector duty cycles dictate if you need larger injectors industry standards usually say as long as your duty cycles are LESS than 80% you are fine---I have STOCK 28# injectors on my apprx 400 RWHP '98 and my DC's are at 90% --but i never run it WOT for a long time to let them overheat--Even on track days at the dragstrip it all works fine.
REMEMBER larger injectors makes the slow speed and idle tuning extremely difficult as well--

Here's what I got from "Chevy LS1/LS6 Performance" book by Chris Endres:
'97-98: 28 lb/hr
'99-00: 26 lb/hr
'01-04: 28 lb/hr (includes both LS1 and LS6)
Personally, my 2001 LS1 had the 28 lb/hr injectors on it from the factory. The stamped part #s on the injector housings don't lie.
