Put the piston at TDC, then use a buret and tranny fluid to measure teh volume required to fill up to the deck height. Then repeat this process on the heads with the valves in. You can now add up how much fluid it took and the volume of the head gasket. You can then plug this into a compression ratio calculator and get your ratio.

Or this:
Compression ratio Calc
You'll need to measure the piston deck height and valve relief volume.
