I may be misunderstanding, but if your question relates to your dished pistons, machining them flat and also machining the liners is NOT the way to increase compression. Pistons are specially engineered, and you can't simply shave off material to modify them without risking big problems later.
One way to increase the compression ratio on the 2.0L is purchase the European pistons, which are flat-topped. This will get you up to 8:1. Beyond that, you can reduce the size of your combustion chambers, but I don't know if that's recommended.
