Hello KASEKENNY1, I completed a cylinder leak test and I followed the air sounds. Turns out the valves were too tight, which kept the valves from closing completely. I had followed the manual, but found out I needed to just barley remove lash and tighten 1/4 turn. Then, I checked each cylinder for compression and most were still too tight, so I turned back each valve bolt until I measured proper compression, which was better than before, albeit, new head gasket. All cylinder valves were readjusted for compression. Truck started immediately and ran awesomely powerful. No tappet sounds, nice and quiet. Thank you for your help!
