What is stock head gasket thickness?? And what compression would going with a 6.0 truck head with a .075 thickness gasket give you for a FI setup? Thanks, <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: What is stock head gasket thickness?? Vince...its not. Atleast not as far as I know. But I believe there are aftermarket head gaskets by Cometic up to .075 thickness.

Re: What is stock head gasket thickness?? The 6.0L CC is only 1cc more than Stock LS1 heads. Cometic does make a .078 which I just finished installing. My LS1 Head C/R with the above gasket should be 9.6:1
It's 30% thicker than the stock gasket.

Re: What is stock head gasket thickness?? If you order direct from Cometic, you should get them VERY fast. Got mine in 3 days I believe.
The thicker you get, the more pricey they are. These are the same boost gaskets Lingenfelter uses on their twin turbo.
The p/n on my invoice is:
p/n H1294078S LS1 3.910" Bore .078" MLS
$125.95 Each x2

Re: What is stock head gasket thickness?? Yes to both. I'd probably try the new GM 2002 MLS Gasket before the Felpro. I've seen some Felpro's fail on LS1's.

Re: What is stock head gasket thickness?? So assuming I wanted stock bore size, and one or two grades thicker, what would I ask for? I don't know what the stock thickness is for a regular 1999/2000 LS1 (2000 block, 1999 heads)

Re: What is stock head gasket thickness?? I believe the stock LS1 compressed head gasket thickness is 1.33 mm or 0.0524". <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: What is stock head gasket thickness?? FWIW,
No detonation issues or throttle response problems with the new .078" gasket. Car feels great! Hard to notice a 2% loss @ 9.6:1. No direct ATAP results yet. Will pull the data soon.
