Wow good write up. I find it interesting that the HS had burnt the push rod ends. Were they the only ones tested without and with push rod oiling? I will definitely get oil thru push rods now with either rocker assy we end up with. The engine you are testing has a more aggressive camshaft than mine. With a true 1.6 ratio we would end up with .673 lift at the valve with zero lash. That is .093 more than current lift. As you mentioned in the article about the trade off with more lift is extra wear and strain on components... In my situation should probable check ptvc if different rockers are chosen.
