hmmm, interesting, so the notches are used for correct orientation is that so the oil holes line up with the rocker shafts? it looked like the holes were lining up properly. what happens when they run backwards, is that the galling i am seeing? (btw not sure why i started putting a k in front of notch, lol)
Another troubling thing i came across...should all the hydraulic lifters move when i press on them? some of them dont push down....(now that i have both rocker shafts off, i went to each push rod and push it down with my hand and some of them compress and some dont)
