Question LQ4 dish?

Did a search, found no exact answer.
I need the dish CC volume on the stock, LQ4 piston.[2005].
If available, I'd like to see the calculations for C/R w/ stock gaskets and stock LS1 heads. [Looking to get close to 10:1, without milling, piston change.]
TIA,

if you do 5.3 heads I would cut it for 2" valves


just saying. Or you could get some 241s and mill them I think approximately .010 and acheive 10:1. I know you dont wanna mill but there would probably be a lesser cost with milling a set.
