Default c/r question

Ok, so i'm going to be putting my RS heads on my EJ22 and need to figure out what my CR is gonna be. Stock on the ej22 is something like 9.6, however I know the RS heads have more volume than the single port ej22's. I'll be turboing it, but need to know where i'm starting out at (and also need to decide on thick or thin headgasket). I'm hoping to get around 8.7, but I need to know what it'll be. I've tried all the compression calculators and i've gotten everywhere from 7.7 to 11.

anyone help me?!?!!

'97 EJ22 block, '99 RS heads, can get numbers from here:
