curious about valve lash setting/check

Check both ends of both shafts looking for the notch. The notch is a machined gutter over one the sideways facing tube edge and is something like 5/32 wide, I'm guessing. That is a lil more than .125 but not as much as .188,lol. You'll know it when you see it.
If you don't orient this notch to the left and down, then your shafts and rocker arms will not get the oil in the right places and galling is soon to follow.
If your tubes do not have notches, you be in big twubble.:poke:
