IMO, 10 psi signifies fairly significant wear, and is probably enough leakage to create positive pressure in the crankcase.

The baffles will likely help a lot. Like SSMonty said, check the PCV valve and make sure that the entire PCV system is set up correctly.

You need filtered air going in on one side of the engine and a PCV valve connected to manifold vacuum (quite often from a carb spacer plate on a Ford)
