Atlas Rocker Spindles

I am thinking the only purpose of the flats on the latest Commando spindles is for orientation of the oil hole ...... lt keeps meaningful the instructions in Norton service manuals that say to locate the flats outwards.
If this is correct, then plain spindles with no flats should be installed with the oil hole facing same as with newer Commando spindles with flats facing outwards.

It would not hurt a thing to use new plain spindles with the flats. Just face the flats away from the center of the head.

That is how the head in my '67 Norton 750 engine is set up and I do not have an over oiling issue. Spindles with flats are what came in '67 750 engine heads when they were built new if one is to believe the instructions in the Norton Villiers manual I have that was first published in March 1967.

I'm not sure why Dunstall used the plain spindles in the head unless that is all they had laying around the day they put it together.

Could be right?
