Between my engine builder and myself we decided to go with the T&D rocker arm system and push rod oiling at build. This was my engine builders first use of said rocker system on FE engines. He called T&D for advise and got very poor directions. He decided that .125" restrictions were required for the rockers at the head oil ports.
After an accidental find that there was way too much oil to the top end I called T&D myself and was told that I need to plug the head oil port completely because we had decided on push rod oiling. Can't have both.
This issue has now been resolve and after some more fine tuning I have also eliminated the issue of rich idle by playing with timing. I was running 32 degrees total timing. I increased total to 37 degrees which made a big difference. Now runs much cleaner at idle. Didn't check initial, so don't even know what it is.
All is now good.

I'm running 0.060". The oil quantity is sufficient for my Ersons and there's no oil ponding.

It's always a plus to have a builder that's REALLY knowledgeable on FEs.
Right sized FE head oil restrictors is sort of "FE 101". O.125'" from jump street is waaay oversized, IMHO. Especially true if using a high volume/pressure oil pump.
