Default Lq9 Compression Check

I am terrible with the calculators and wonder if someone knows a simple way to see if this will work.

stock LQ9 bottom end and untouched 317's is supposed to be 10 to 1 compression with the .051 gasket

Change to the lingenfelter .075 LSA/LS9 gasket

How much will my compression drop?

I have seen somewhere around 2.2CC's gained per .010 of HG thickness but I'm not sure if that's right

going by that I should be ~ 9.47

am I totally off or decently closer here?
I wanna cheaply turbo my LQ9 this year and do a rods and piston setup next winter...
