Re: Too much oil in head?

Not oil supply to the cam bearing, just oil drain from the exhaust cam valley to the intake cam valley where oil drains to the sump via the pushrod holes.
Drilling the rear drain would be a challenge as if passes above the water jacketing core plug and below the spark plug valley .
I have seen a head with an internal leak of pressurized water into the oil drain at the point where the drain passes above the core plug.
