There was a 4-front version of dawn of the dead that had no gore in it...I shit you not.
Yeah, that one I had to keep for the giggles.
The only major gore scenes to stay in were the helicopter gag and Stephen's headshot. Of course there were various headshots still kept in but they were not the messiest of the bunch. Virtually everything big was removed. For example, the 107 basement clean-up was two gun shots long.
