Default Fel Pro gasket part numbers?

I'm trying to find all the part numbers (and bore sizes) for the Fel Pro gaskets for LS1s.

Does anyone have this info or a link to this info?

I know that for a 4.125" bore it's 1041, but other than I don't know.

Just my opinion, but I still think the factory graphite head gaskets do the best job at sealing.

This is from SDPC (our sponsor) > > > > > > > > > over there > >

This head gasket kit for 1997-2001 LS1 / LS6 engines from GM Performance Parts contains a [pair] of head gaskets. Composition OEM replacement gaskets for 5.7L engines. Contains one LH and one RH gasket. Approximate compressed gasket thickness is 0.056"

Price: $34.95
Part# 12498543

Tin indian, I think camaroguy is building a big bore, in that case I think the Fel Pro's would do the best job.

eventually (next year to year and a half) I want to do a big bore motor.....

but when winter brake rolls around, I am thinking of pulling the heads on my current motor to check things out, possibly flycut the pistons (with the Isky tool), and install a larger cam (already own) to hold me over till I can make some REAL hp.....when I do this I want to put the lower thickness FelPro gasket on to bump the compression up some more (someone said its good for 9cc's or .3 CR rise)....
