Keep the EGR.
I have removed the egr on my 94 L67 that is ran by my 92 ecm and drove it for 20,000
without any problems, it still has all its valves and it still has all its rings
so in my opinion do what you want
and runing nitrous wont matter its not going to be the lack of egr that will burn the valves it will be the amount of nitrous and and willwren if you tell me that egr is closed at WOT then tell me when would personally would activate your nitrous at 1500 rpm??
We were picking Mariks brain to see exactly where he was going... We thought it would be a driver... We were keeping that in mind... Its going to be an all out race Van...
Funny how GM killed off the EGR on the L27 engines for 90,91 and 92 only to add it to the 93... the 89-93 3300 was also EGR'less ... Now the L27 and L67 are different in terms of NA and SC...
But, In 93 GM reinstalled the EGR on the L27, they didn't do this to the 3300 as 93 was the last year for it.... I have seen a series of L27'* and 3300'* that had burnt valves... Some did some didn't... And GM did not reinstall the EGR for emissions, it wasn't even needed.. But it sure did solve the issue of the Burnt valve syndrome...
I have seen some with less than 100k with a burnt valve or 2... Others never burn a valve
