Default Ls 2 ls6 243 head flow numbers

I've searched the net and found flow numbers anywhere from 248 to 278cfm @.600 lift.

Is there anyone on here that has had these heads on a flow bench with a ls6 bore size 3.9''and tested them with that instead of a4''bore that will give higher flow finggers please.
I want to see what they really flow on a ls6 bottom end.
