When the shaft is properly oriented, the oiling hole and corresponding slot is covered by the rocker arm radius, preventing excessive oiling!
I'd pop the rocker shafts , or at least loosen them slide a rocker over (if you can) and verify that there is no hole on the top of the shaft!
Cheers!

That was the first thing I checked, and they are installed correctly. I also checked and confirmed the correct valve seals. Like I said, the problem has abated. I think the engine builder just didn't hone the cylinder walls correctly.
