.052 compressed ... found it here:
It was buried but enough searching finally yielded the answer. Since Jerami last edited the table on 05/29/2005, I'd say it's likely accurate. I'd also say it's for the later model LS1's ... however, I have no idea. Anyone know? All I know is the later model cars got the thicker GM MLS gasket.
For anyone new or anyone who has read it in awhile, I found it was good to go back 'cause I missed or forgot alot of the great information. Thanks to Jerami and other folks who have dedicated so much of their time to provide us with their knowledge and research.

i dont think well ever get a 100% no if and or butts definative answer; i've heard .052, .054, .060 for the MLS. i think its akin to deck height, everbodies is justs a little bit difference. best think to do would be just purchase a set, mic it, and use that measurement to figure out your compression and quech relative to your own motor. i wonder if GM has a tolerence range for there gaskets....
but **** if i care as im running a .045 cometic
