No oil coming up through my push rods.

Have you ruled out an exhaust leak? Get a piece of hose and use it to listen around the header flange. Look for soot around the exhaust ports as well. I thought something was wrong with my valve train and it ended up being an exhaust leak. Second time I had a nice ticking noise, it was a mushroomed valve stem. It was noticeable without removing the rocker arm shaft. I would remove the shafts and inspect the valve stems real good for signs of wear. Maybe the stem height is incorrect. I attached a few pictures from the manual on the proper orientation of the shafts and rockers to help if you haven't already checked that. There's a notch in the shafts. Left shaft: faces forward and down. Right shaft: faces to the rear and down. It's easy to remove and reinstall those shafts and it'll give you piece of mind. Good luck.
