Apparently 98-2001 (or 2002) are suppose to use graphite, the MLS headgaskets which are better, will not work as they will leak water due to some notch issue.
I can't take the risk it worries me.. I found the GM performance MLS but due to this issue would pass...
I found this headgasket kit but never heard of 'engine tech' it is MLS and apparently would work for my 2000
not sure i follow you when you say " due to this issue would pass"?
you can swap graphite to the mls but you will have to check your push rods to ensure proper specs
Hmmm, is that for sure? I just was worried about that as I read it on LS1tech and some other LS related forums people mentioning that, and I figured I might as well ask here. Those were older posts.
Anyone else can confirm. It seems to be an issue due to head differences in the pre 2001 engines... some kind of 'notch' that is talked about which would cause water leaks...

I used those Enginetech gaskets and they worked great on my '02. The exhaust manifold gaskets wont work with '01-'04 because of the location of the AIR tube. Not sure about earlier models.
contact a site vendor
someone like Texas Speed they will help out.
I would not use the graphite due to the effort to clean them off should
ever change heads etc. I bet they were a pain to get surfaces clean.
MLS gaskets are what GM uses for all of the SC setups and will serve you well.

believe it or not, a lot of reputable builders use ls9 gaskets on high hp forced induction build regardless of the bore discrepancy between the ls1/6 and ls9

You can likely find out of if you have the notch by the casting # on the head if you have an early C5. I know on 2 2000s we did not have the notch, and used MLS gaskets.
