Default LS2 stroker with L92 heads gasket size

Do the L92 heads use a 4.03 bore gasket for use on the LS2 block or does the combustion chamber extend beyond the 4.03 requiring a larger diameter bore gasket?

I believe the standard bore on a L92 block is 4.065. Someone please correct me if I am wrong. Hope this helps

You need at least 4.065" bore gasket which is L92 size. There is really no downside to runing gaskets for 4.125 bore.
I am running LS7 sized .040 Cometics.

Yeah i think the L92s require a 4.000 bore or larger which you are ok with but i think most head gaskets i have seen for these heads are 4.160, i may be wrong though

Guy, I replied on the other forum as well and sent you a PM. And for the record over here so the answer might spread and be known by all: 4.0x" bore and L92 heads need a head gaskets with a bore of 4.085 or so (GM's gaskets for this ranges from 4.09-4.10"). We keep the Cometic gaskets and the GM MLS gaskets in stock!
