Larger valves are not required on a cvh anyhow. They actually impede flow.
originally i assume they did flow test it as it was part of a system 2 ebgine package they used to sell. Im now using it on my ZVH so im guessing the big valves would help. Would you know if opening up the oil ways in the head help?
Here are a few pics perry, not that you would be able to say if its good or bad without a flow test.
