boosted_hatch_216

does anyone know what compression this would put me at on a mini me with a z6 head on a a6 block. i got 9.7 but im not sure if that is correct and i wanted to see what everyone else came uo with and do you think this would be too high for a boosted d? probably at about 15 psi on a to4. forged rods of course. just wanted everyones input. and where could i get a headgasket that would help lower that compression and how much would it be roughly. thanks for the input.
