273 rocker arm adjustment

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)

Yea the banana grooves, i could see that being helpfull, my ford 390 has them. are the machine shops setup to do those?

I am worried that my lifters are damaged now... i am not seeing the benefit to switching to 273 adjustable rocker arms, and now i am worried about the cam.
