The 59 series and earlier had the oil pressure relief valve outflow to oil the timing chest so they would be kind of wet. The 8BA has a different crankcase ventilation system and no relief valve in that area. The thrust of the cam is different as well. Oiling isn't as critical in there as it was in previous designs. If you alter the designed outflow anywhere in the system, it will also alter the oil pressure. As long as that port is open as designed, it will get the amount of oil the design intended. Ford was using the fiber gears too so they would run with less noise.
