You got low compression because all your valves are partially open at the same time like that. One up. One down.
Here's a picture.

I don't know shit from these pins, but I know a search would be helpful. I recall seeing people discuss this before. Even so, take your stock gears and see how they go on. I don't think it should really matter, so long as one is up and the other is down, but if you can see the stock exhaust gear reading "2.0L front" correctly, then make the intake cam the opposite.
