It would take something like some 6x-4's milled to like 85cc's on a zero deck shortblock to get close to 11.0:1 CR with those pistons (that's like 10.94:1 CR).
The dome on those pistons is pretty dang small,only like +10cc's compared to the flat tops that are -6.6cc's or so.
FWIW/HTH

I figured i could get 10 to one or more outta that setup...i know, i have to mill the intake side of the heads too... i would go zero deck or even maybe .005 out.
