Squirt hole or no squirt hole?

If you read the FSM, it clearly shows the oil squirt hole is for the bottom of the cylinders. It's intended design has nothing to do with the camshaft. If there's benefit to the cam from the squirt holes, it's very minimal, IMO. If the camshaft doesn't get enough splash lube from the crankshaft and rods slingin around, somethin's WRONG.
