I have read that the LS9 gasket has a bore of 4.100 and the chamber width of my L92 is 4.125.. Would this matter any? Im talking a big power motor I have 1,000 to the ground from a PT101 at minimum boost (18psi) and blew a cometic the other day, noticed other head was pushing water on all four cylinders, The block feels smooth to the touch where it blew, the heads are gonna get .010"-.015" off the decks as a precaution.

Use them. Lots of guys are using them without problems in pretty much everything, including small bore stuff like the 3.78 bore 4.8 and 5.3. Including me.

I used them on my old 408 combo worked great, go for it!
