Default LSX Bowtie block questions

what is the minimum bore that the lsx comes with? I only ever find data on how big you can take it out. But im more interested in keeping the walls thick as hell.

Also, does GM sell an LS9 type headgasket for the extra bolt holes? or do people just run the standard gaskets? what options are there?

Pretty sure they come out of the box with a 3.99" machined bore.

Thanks, I talked to a machine shop yesterday and they confirmed this!
