That would be very unlikely. There are no oil passages, and therefore, no pressurized oil in the heads. The heads only provide for gravity drain back of the oil introduced through the push rods. If there is a way in the gasket for oil to find it's way out, the opening would have been caused by something else leaking much worse.

RACE ON!!!

agreed.

A great source for an oil leak is the pan gasket itself. They work a bit loose, and as the oil works down the block, and gets splashed inside the crank case, it gets messy... icky-poo, really.

Another source is the valve cover gasket and intake manifold gasket.

Front and rear mains, they are famous for leaking.
