Your actual compression ratio will change depending on the cam you choose. Most cam manufacturers will recommend a certain static compression ratio for any cam they make. The static compression ratio is the volume of the cylinder with the piston at BDC divided by the volume of the cylinder at top dead center.
The dynamic compression ratio (what the engine actually runs at) will not only depend on piston selection, head gasket thickness, head selection, etc. but also on the valves opening and closing. To figure what your engine will actually run at, you need to use the cam specs.
