it'* a little more complex than that
i have a 96 w/original intakes with nary a leak in sight and over 100 mark on miles - it'* more than miles - there was somthin about the original lower (which i have *not* been able to track down yet) that caused them to have different egr stovepipe characteristics. not sure if it'* a metalurgical thing going on or not, but it seems that different lower intakes have more or less distortion because of the egr.
as for dorman intakes, like willwren said, we haven't seen one fail yet. no real way to know if one will - it does have the extra beef. now the real tossup is if that'* enough beef, but i wouldn't worry myself too much about it - just continue checking your coolant level at oil changes (never a good idea to just ignore it anyway), but don't feel like you have to be as paranoid as you were before - you do have extra protection.
side note: i do work for gm, but do not take this as an official saying or word from gm, cause i really do like my job
