Before you go making changes, how about posting clear, close-up photos of the present pulleys. Clean them so that any markings stamped on them are legible. From that, I can tell you if they're installed with the correct side facing forward. If they are correct, and the timing marks are correctly aligned, then that's all you need to worry about. It's NOT about three teeth, or anything like that. Just install the pulleys and properly align the correct timing marks, and all the rest will take care of itself.
If you follow correct procedure and get the pulleys and the belt installed correctly, and the compression pressures and/or leak down rates are still bad, then the problem is in the engine somewhere and messing around with the cam timing won't fix it... but it can make it worse.
The 907 is an interference engine, and timing errors or experiments gone wrong get very expensive in a split second. This isn't the place for guessing, or 'taking a shot at it'. Show me good pictures.

Out of curiosity, where did you buy the Gates T104RB belt?
