I watched your oil pressure on the last ride, and I saw no sign of wide tolerances in the mains/rods, so I would inspect the block deck for any pitting/lows with a good straight edge and feelers, clean up the deck with a good scraper and maybe a judicious application of a big flat file to knock of any pulls around the head bolt holes (gently, gently with this - it's kinds rednek), and flatten the heads and do the guides/seals, and lap the valves and call it good. I saw it poot a couple of puffs of oil smoke after an in gear decel on the ride, and it sure looked like stem leakage to me, and also smelled that way. Burnt oil from gone rings smells different from vaporized oil from leaking exhaust guides, and vaporized is what I smelled from yours. You may not have perfect ring seal, but I don't think it's time to yank the motor. New vla's might not be a bad idea, though...
