You want to check it in comparison to the other 5 and that will let you know. There can be guides needed or cutting the faces of the valve or just a carbon build up on the valve face keeping it from closing completely.
If the engine is on the floor, any numbers would be suspect without running it through several heat cycles.

You really need to do a leak-down test to diagnose the problem. With a leak-down, you can listen for the source of the leak and get a much better idea where the problem is.
