No oil coming up through my push rods.

this is why I asked if the pushrods are spinning while the engine is running. If the lifters are spinning as they should, then so should the pushrods.
An easy way to check if your lifters are spinning is to paint a dot (or silver Sharpie) on each pushrod and crank the engine over and make sure the pushrod is turning. If not, the lifter or cam lobe could be toast.
