If I turn the crank by hand will that push any oil up there or do I need significant oil pressure from the pump?

With the head off and with the help of an assistance, cranking the engine with the starter should bring the oil up the hole in the block deck. Be sure the fuel supply is disconnect from the fuel pump to prevent fuel from spraying everything (if electric fuel pump, be sure to pull the fuse) and causing a fire.

Thanks James! I'll give it a whirl. Hoping I don't have to tear the whole thing down to get at a cam bearing......
