PCV leak

Believe me the carb and timing have been optimized. Using my vacuum gauge, several different setups 10 inches is all it is going to make, started at just under nine inches.
The current PCV must be working to some extent as I have no oil puking into the air cleaner.
OK on the optimization.. just wanted to be sure that step was being done.

Yes, of course it is working. It is in wide open mode all the time.... that is cruise mode so is going to pull all the oil fumes out. But you need a PCV that will drop to low-flow mode when the vacuum levels rise when you are at idle or very light throttle openings.
