Default Patriots stg 3 LQ9 head gasket question

As I undersand it.....the stage 3 patriot lq9 heads have a 4.125 bore. I am using these heads on my stock LS1 bottom end (3.910 bore I believe) for a turbo build.

What head gasket should I use? What bore? Thanks in advance.

This is not correct. The stage III LQ9 heads are set up for a 4" bore unless ordered for the large 4.125" bore. We have many customers that use the GM MLS 6.0 gaskets when putting the LQ9 heads on a LS1.
